-Product Description 
To weld end covers to tank shell. MAG welding process or others as needed. Full automatic available. -Specification
Welding process:
welding process is single-sided welding double-sided molding, Welding speed requirement ≥800mm/min Welding torch shielding gas: Ar /100%; Shielding gas: Ar/100% (for back protection of electric water heater tanks).
Automatic:
load&unload, positioning, fixing, welding and so on. Double and single head circumferential seam welding machine1.This equipment is mainly used for automatic welding of 1.0~2.5mm thickness tank body and heads . The tank is rotated and the torch is fixed. Use double-head mixed gas protection welding method. Applicable materials: carbon steel, stainless steel, etc.2.The welding power supply is equipped with OTC500 welding machine, wire feeder, air-cooled welding torch and 2 sets3. Tank requirements: length is 300 ~ 1000mm (including end), diameter 340mm, roundness ≤ ± 1mm, the wrong side of the middlebodyis ≤ 1mm, and the matching end cover mould size is φ340mm

Longitudinal seam welding machineLongitudinal seam welding machine is mainly used for semi-automatic welding for 1.0 to 2.0 mm thickness electrical water heater tank. The action mode is tank fixed and welding torch moves. The process uses TIG welding and is equipped with an automatic wire filling mechanism. The equipment is suitable for welding such as carbon steel and stainless steel raw metals. The welding power source adopts Miller Maxstar400, the welding length is adjustable from 0-800mm, suitable for the Ф 340 diameter electrical water heater tank.
Water pipe&Sewage discharging pipe welding machine1. The water pipe welding machine is a special equipment for realizing the automatic welding of the tank body and water pipe; mainly completed by the rotation of the welding torch. Adopt MAG welding method, air-cooled welding torch, power supply adopts OTC400 2. Automatic welding of different size structures can be satisfied by adjusting the positioning fixture. 3 The welding station is designed with a lifting bracket, which separates the tank from the conveyor chain during welding.4. The height of the wire feeder should be as low as possible to facilitate the loading of the wire spool. The torch cable passes directly from the center of the shaft of the rotary head, and the direction of rotation is always in one direction.
