13kg 45kg Customized LPG Gas Cylinder Automatic MIG Circumferential Body Seam Welding Machine

Description

PROCESS STEPS
LPG Cylinder Production is composed of several sheet metal forming, surface treatment and testing processes. The process starts with blanking, deep drawing and piercing, trimming and joggling. Next are the welding operations for valve boss, valve guard ring, foot ring and the two halves. The finished cylinder is then heat treated, tested, shot blasted, painted and then the valve is attached and final tested.

LPG Cylinder Blanking & Body Forming Line

In the core of the forming line there stands a versatile double action our hydraulic deep drawing press that forms the cylinder halves out of round blanks that are blanked by a single action double blanking our press or directly from the coil material by help of our design combined deep drawing, piercing and blanking die set. The edges of the upper and lower halves are further processed by our trimming and joggling machines to the perfection stemming from the sheet metal forming expertise of our to make it read for the body seam welding after degreasing.

LPG Cylinder Body Forming Welding Line

The submerged arc welding technique is applied on the welding of body halves on the seam welding machine and generally on the welding of the valve boss to the upper cylinder halve. The welding automatic with reliable welding power packs and control units are utilized to achieve the uncompromising weld quality with degree of automation needed for the required production capacity per customer. The MIG/MAG welding technique is applied for the welding of foot rings and valve guard rings with the body halves. Welding is the most critical part of the production line, which engages the best cylinder performance and assures the good quality. Our welding machinery is the best cylinder & pressure vessel welding equipment in China and also TOP Ranked worldwide.
Full-auto welding machine includes socket welding, handle/collar welding, base ring welding, circumference welding, and all machines work automatically, the cylinder halves are conveyed by mechanical arm and chain, this system really saves much labor cost and improve the working efficiency apparently. In order to relive all the stresses caused by forming and welding operations, the cylinders are passed through a heat treatment furnace where they are exposed to 930 º C degrees of temperature for certain time before getting cooled gradually.
