What is an LPG Cylinder Circumferential Welding Machine

LPG Cylinder Circumferential Welding Machine is an automated equipment specially used for automatic welding of girth welds of liquefied petroleum gas (LPG) cylinders. The fabrication of tubes or piping systems requires precise welding around the circumference to ensure the quality fusion of the material. Circumferential welding describes processes that can weld two cylindrical pieces by welding around their outer diameters to fuse and form a single entity. Circumferential welding, a term synonymous with orbital welding, has been preferred by welders for faster operation and higher quality welds devoid of defects.

Types of LPG Cylinder Circumferential Welding Processes

Metal Inert Gas Welding (MIG)
Also known as gas metal arc welding (GMAW), or wire welding, this welding process utilizes continuous wire feeding as the consumable electrode traveling along the circumference. The process includes a shielding gas that prevents any contaminants in the air from corrupting the weld quality. However, this need for purity can also be a drawback as environmental factors can influence the effectiveness of shielding gas and cause weld quality to diminish. Nevertheless, the relatively faster welding speed and increased deposition rates allow welders to achieve higher productivity.

Tungsten Inert Gas (TIG)
Otherwise known as gas tungsten arc welding (GTAW), this welding process has been used by operators for welding ferrous and non-ferrous metals. The process utilizes a non-consumable tungsten electrode to create an arc and inert shielding gas to prevent oxidation and contamination. The process can be more complex when compared to other welding processes, but GTAW can perform purer and more consistent high-quality welds.

Laser Beam Welding (LBW)
This welding process leverages a concentrated laser instead of a conventional electric arc as a heat source for creating a weld. Although it creates a smaller heat-affected zone, LBW depth of penetration is limited when compared to TIG welding. However, the process is effective in welding thin-walled materials.

Plasma Arc Welding (PAW)
The plasma arc welding process is similar to TIG welding, as they both utilize a tungsten electrode to create an arc; however, a plasma arc is used to generate heat. Its arc control can produce excellent quality welds on thin to thick materials; however, it can create a comparatively larger heat-affected zone than TIG welding and can be costly.

Frequently Asked Questions

Q: How is the welding machine calibrated to ensure accuracy?

A: To calibrate a welding system, you need to connect the equipment to a calibration station. The station measures the wire feed speed, voltage, and amperage of the tools and determines the gas flow rate of the welding source.

Q: Is real-time monitoring of the welding process available?

A: Various types of optical sensors have been applied to provide real-time monitoring of welding parameters, such as arc length, weld pool oscillation and weld pool size measurement. The weld pool characteristics provide important information about the weld quality.
