Electrogas Welder EGW-P

December 3, 2017 by Luke Guynup

EGW-P | Electrogas welder, is an unmanned vertical welding machines EGW = Electrogas arc welding machines or (Electrogas Welder) which is also know as a (AVW) automatic vert welder or VUP welder are high efficiency automatic welding equipment which achieve closed-loop control of carriage lifting via current feedback; Welding joint one-step forming thickness is 50mm, mainly used for thick plate single pass welding in petroleum, chemical, blast furnace and ship building industries.

Compact non operator carrying vertical welder that runs on shells for max flexibilityEliminates limitation on plate width for conventional vertical weldersSuitable for general heavy wall vertical welding for tanks (repairs and construction), vertical cylindrical structures (piles, offshore jackets, chimneys etc) and vertical panelsEconomical but sufficiently robust for heavy duty welding operation.Specific models welding on inclined surface (eg. tank roof, inclined piles)

The EGW Single Pass Vertical Welder is a high productivity automatic vertical welding machine which uses real time closed-loop monitoring of the welding arc to accurately locate, control and adjust the welding head in the weld joint via arc current feedback and automatic carriage travel. This is used to complete single pass welds in material from 9 to 36mm thick but can also be used to complete thicker plate welds of up to 70mm when welding on both sides of the joint. This machine is used for vertical plate welding in the storage tank and many other applications.

Vertical Welders Features

  • Adopts EGW (Electro Gas Welding) process for high speed carbon steel vertical welding with FCAW (Flux Cored Arc Welding) Process option for alloy steel vertical welding
  • Lightweight travel carriage, self-propelled, weatherproof, fully contained operators cabin which allows safe access to the weld joint and easy set up and install
  • Lightweight Aluminum track, quick mount electro magnets , easy assembly and disassembly;
  • Real time monitoring of arc and automatic control of weld pool level, welding gun position and automatic adjustment of electrical stick out;
  • Sequence control in “Auto mode” to allow one button startup.
  • Onboard- self-contained continuous water cooling system
  • Fully integrated with LINCOLN electric welding systems as standard (other welding systems on client’s request)
  • SEW drive system for reliable and steady travel
  • Different standard configurations for site erected Bottom Up and Top Down erected storage tanks or heavy wall cylindrical structures (eg. towers, blast furnace).

Applications:

  • Adopt unmanned rack, small volume, light structure, convenient assembly, and disassembly, flexible use.
  • Used in small and narrow space, mainly used in petrifaction, coal mine and electric power industries.

A list of automatic vertical welders we offer: 

EGW-V: (Electrogas Welder) upward installation electrogas (arc) welding machine, for traditional storage tank welding; which is also know as a (AVW) automatic vert welder.
EGW-V/D: (Electrogas Welder) inverse installation electrogas (arc) welding machine, for jacking construction of storage tank; which is also know as a (AVW) automatic vert welder.
EGW-P: (Electrogas Welder) light weight unmanned electrogas (arc) welding machine, mainly for power generation and wind tower welding; which is also know as a (AVW) automatic vert welder.
AVW-Multi pass is a multiple pass automatic vert welder that uses gas shielded FCAW for low heat input multiple pass (FCAW / dual shield) arc welding, specially designed for field work construction of special steel brands (such as low-temperature steel and stainless steel)
