The girth welder is an automatic welding machine that straddles the tank plate and is used to complete a tanks circumferential weld joints. It’s typically used in a single or double sided configuration. In the single sided configuration one operator is required and welding on one side of the joint occurs. In the double sided configuration two operators are required and welding occurs simultaneously on both sides of the weld joint.

Use of girth welders will offer increases of productivity of by up to 10 times as opposed to manual completion and with the additional benefit of improved weld quality.

AGW Tank welders are a series of self-propelled Automatic Girth Welders (3 o’clock) welding equipment primarily developed for on-site erection of large storage tanks, silos, blast furnaces and similar cylindrical objects. It is available as a single-side version and a double-side version. Usually it is designed to travel on the top edge of the tank shell. As there are different ways of building tanks, one machine in the series is designed to travel on a rail which is temporarily fixed to the shell or on a stand-alone ring outside the shell. This line of equipment is built to the European CE standard and to other standards upon request.

The operator of each machine (of the full size version) rides in a cabin, where he supervises and controls the welding process with the control panel within easy reach. The cabin, whose floor level under the carriage is variable to suit the height of the plate, is built as a cage to give the operator(s) maximum safety and comfort. For weather protection the cage can be covered by curtains. The cabin of a double-side machine is equipped with ladders our an internal frame climbing system and a joining bridge at the top to facilitate for the operators to climb from one side to the other. The top and bridge has guard rails for the safety of the operators.

An AGW is the machine used to automatic weld the circumferential weld inside and outside of vertical storage tank. By using AGW machines to replace manual welding the on-site storage tank welding time and welding defects can be significantly reduced.

AGW basic components include the frame, machine head mechanism, control unit, flux towing, flux recovery system, welding power and the storage case.

AGW1-EX / AGW2-EX is an Automatic Girth Welder | AGW | 3 O’Clock Welder | Tank Welder built with an expandable and removable lower frame to fit in the narrow space of double wall and flat bottom tanks. It also has clearance to weld over shell plate stiffeners. AGW1-EX is a single sided machine, AGW2-EX is a double sided machine:

With an additional upper frame two of the AGW1-EX single sided machines can become 1 double sided AGW2-EX Automatic Girth Welder (AGW) which is also know as a (3 O’clock welder) built to fit in the narrow space between the outer tank wall and the inner tank shell plate to perform low-temperature storage tank automatic girth welding. AGW1-EX / AGW2-EX are available in standard proven designs and custom built-in single or double sided configurations. MPS = mobile power source is another option that can be added to most of the full size AGW’s we offer.

The AGW Tank welders are a series of self-propelled Automatic Girth Welders (3 o’clock) welding equipment primarily developed for on-site erection of large storage tanks, silos, blast furnaces and similar cylindrical objects. It is available as a single-side version and a double-side version. Usually it is designed to travel on the top edge of the tank shell. As there are different ways of building tanks, one machine in the series is designed to travel on a rail which is temporarily fixed to the shell or on a stand-alone ring outside the shell. This line of equipment is built to the European CE standard and other standards when requested.

The operator of each machine (of the full size version) rides in a cabin, where he supervises and controls the welding process with the control panel within easy reach. The cabin, whose floor level under the carriage is variable to suit the height of the plate, is built as a cage to give the operator(s) maximum safety and comfort. For weather protection the cage can be covered by curtains. The cabin of a double-side machine is equipped with ladders our an internal frame climbing system and a joining bridge at the top to facilitate for the operators to climb from one side to the other. The top and bridge has guard rails for the safety of the operators

Applications:

  • Double wall storage tank welding can be equipped for AC welding or DC welding applications
  • Standard AGW1-EX / AGW2-EX by design can weld plate width up to 3.8m without modification, 4.5m wide plate with some minor modifications and a custom built AGW1-EX / AGW2-EX can weld plate wide as 7.5m.

The girth welder is an automatic welding machine that straddles the tank plate and is used to complete a tanks circumferential weld joints. It’s typically used in a single or double sided configuration. In the single sided configuration one operator is required and welding on one side of the joint occurs. In the double sided configuration two operators are required and welding occurs simultaneously on both sides of the weld joint.

Use of girth welders will offer increases of productivity of by up to 10 times as opposed to manual completion and with the additional benefit of improved weld quality.

AGW1-P2

The AGW1-P2 Automatic Curved Plate Welder is an AGW which is also know as a (3 O’clock welder) has been developed to run on a rail for welding out of standard position girth seams on pressure vessels such as Spheres & Digesters.


AGW Stiffener welder is a new custom built automatic girth welder that has been built to run on top of the tank shell plate as other AGW’s however is has been designed with a wide range of vertical adjustment (top to bottom) not normally found in a AGW allowing this AGW to weld stiffeners onto the tank shell plate located in most elevations.

AGW stiffener welder


The girth welder is an automatic welding machine that straddles the tank plate and is used to complete a tanks circumferential weld joints. It’s typically used in a single or double sided configuration. In the single sided configuration one operator is required and welding on one side of the joint occurs. In the double sided configuration two operators are required and welding occurs simultaneously on both sides of the weld joint.

AGW Tank welders are a series of self-propelled Automatic Girth Welders (3 o’clock) welding equipment primarily developed for on-site erection of large storage tanks, silos, blast furnaces and similar cylindrical objects. It is available as a single-side version and a double-side version. Usually it is designed to travel on the top edge of the tank shell. As there are different ways of building tanks, one machine in the series is designed to travel on a rail which is temporarily fixed to the shell or on a stand-alone ring outside the shell. 

The operator of each machine (of the full size version) rides in a cabin, where he supervises and controls the welding process with the control panel within easy reach. The cabin, whose floor level under the carriage is variable to suit the height of the plate, is built as a cage to give the operator(s) maximum safety and comfort. For weather protection the cage can be covered by curtains. The cabin of a double-side machine is equipped with ladders our an internal frame climbing system and a joining bridge at the top to facilitate for the operators to climb from one side to the other. The top and bridge has guard rails for the safety of the operators.

An AGW is the machine used to automatic weld the circumferential weld inside and outside of vertical storage tank. By using AGW machines to replace manual welding the on-site storage tank welding time and welding defects can be significantly reduced.

AGW basic components include the frame, machine head mechanism, control unit, flux towing, flux recovery system, welding power and the storage case.

Automatic girth welder characteristics:

  • Standard configuration of the automatic girth welder it the reliable LINCOLN welding system
  • Dual AC variable frequency motor drive ensures that the Automatic Girth Welder could walk along the storage tank stably within a certain speed range
  • The Automatic Girth Welder head is equipped with welding seam automatic tracking system to keep the welding gun position accurately in the weld seam during the welding process.
  • Powerful vacuum pump mounted in the middle part of the Automatic Girth Welder frame to provide an effective flux recovery and recycling system.
  • Additional flux holding mechanism has been added just above the welding head and flux belt to provide a more consent flow of flux to the welding process.
  • The welding machine could be operated conveniently and clearly via the integrated control panel
  • Available in single sided and double sided models for performing double and single side welding of liquefied petroleum gas, liquefied natural gas tanks
