Product Description

Circumferential Seam Welding MIG Welding

1,Circumferential seam welding(MIG Welding) machine for inner and outer bladder

Circumferential seam welding is a very important part of the LNG cylinder production line.
The most important thing in the process is the MIG welding process,
There are many materials for mig welding sheet metal welding wire, mainly aluminum wire, etc.

2,Sub-item description of main welding equipment configuration(Welding host system&MIG welding system)

(1) Machine bed guide rail                                             (2) Column and beam        
                  
(3) Active head                                                               (4) Hydraulic tailstock (including hydraulic tightening)

(5) High-precision hydraulic bracket                              (6) The head and tailstock fixture

(7) Welding head                                                            (8) Arc protection device

(9)  Hydraulic system                                                     (10)Welding power source

(11) Welding gun                                                            (12)Laser weld tracker


3,Circumferential seam welding(MIG Welding) process

MIG welding process is adopted, and 98%Ar+2%02 mixed gas is selecte as the shielding gas. 2.5~5.0mm MIG welding single-sided welding double-sided forming at one time; equipped with Austrian Fronius company TPS5000 digital MIG/MAG pulse Automatic welding machine
(including welding power supply, wire feeder and cable, etc.).


4,Circumferential seam welding(MIG Welding) results

When the workpiece assembly and surface are in good condition, the welding material and the shielding gas are in good condition,
the weld reinforcement is within the range of 0-2.5mm. The one-time pass rate of welding is greater than or equal to 90%,
the appearance is beautiful and the surface is free of defects.




5,Circumferential seam welding(MIG Welding)Equipment structure

The general diagram of the equipment is as follows:


LNG insulated gas cylinder double ring seam equipment is suitable for double ring seam welding of cylinder body and head, and adopts a horizontal machine tool structure as a whole. Mainly composed of bed guide rail, head and tailstock hydraulic tightening, high-precision hydraulic bracket, head and tailstock fixture, column and beam (2 sets), welding head (2 sets), hydraulic system, welding power supply system (2 sets) and electrical control system.
