Tempering is one of the most likely types of accidents when using an acetylene gas cutting torch for gas cutting operations. It is a phenomenon in which the acetylene gas flame enters the torch nozzle and burns backwards. It is characterized by the sudden extinguishment of the flame and a rapid "his

The submerged arc welding process is the most ideal choice for important applications in pipelines, pressure vessels and tanks, rail manufacturing and major construction. It has the simplest form of single wire, double wire structure, tandem double wire structure and multi-wire structure. The subme

(1) The main research object of welding labor hygiene is fusion welding, among which open arc welding has the greatest labor hygiene problems, and submerged arc welding and electroslag welding have the least problems. (2) The main harmful factors of shielded electrode manual arc welding, carbon arc

ARC TYPES IN MIG/MAG WELDINGThere are various arc types in MIG/MAG welding. They differ in terms of the level of the amperage. In the low power range the arc is susceptible to short circuits; in the higher power range it is free of short circuits.DIP TRANSFER ARCThe arc is ignited by brief contact b

PROCESS VARIANTS OF TIG WELDINGCOLD WIRE TIG WELDINGA cold-wire feed increases productivity: The welding speed increases and the filler metal is fed precisely and evenly to the weld pool. This allows even less-experienced welders to achieve outstanding results. TIG HOT-WIRE WELDINGTIG hot-wire weld

Underwater Welding Process

The methods of welding red copper (that is, the so-called industrial pure copper) include gas welding, manual carbon arc welding, manual arc welding and manual argon arc welding, and automatic welding can also be used for large structures. 1. Gas welding of copperButt joints are the most commonly us

Submersion test For small containers or pipes with low internal pressure. Fill the container or pipeline with compressed air with a certain pressure (0.4-0.5MPa) before inspection. Then submerge in water to check the tightness, such as right leakage; bubbles must occur in the water. This is also a c
