Welding Defect - an overview | ScienceDirect Topics
Figure 14.29 shows the welding defects under unsuitable parameters. The defects are usually induced by the improper feeding speed of filler wire and the distance between filler wire and heat resource.The defects shown in Fig. 14.29(a), (b) and (d) are induced by insufficient melting of filler wire when the feeding speed of the filler wire is too high or the distance between filler wire and
Welding techniques explained – Engineering Update
TIG welding uses a non-consumable tungsten electrode and has an extremely high melting point which means that TIG electrodes can heat other metals to their melting points without themselves melting. Argon and helium are the main shielding gases used in TIG welding.

How to Prevent Welding Rod Sticking to The Metal | …
Keep in mind that the melting point of flux is always lower than the base metal. It means that before the base metal even starts melting, the flux is already in a liquid state. If your flux coating is poor, it may fall off the rod and form a molten lump which causes the welding rod to stick to the base metal.

What is Arc Welding? Types, Uses, Basics Working …
Metal inert gas welding uses this type of electrodes for the process of arc welding. Non-consumable electrodes With a high melting point, a non-consumable electrode does not fill the gap in a work piece. Usually in this case the work piece needs to have a low
WELDING - invent. build. enjoy
Merging of metal parts as a result of heating up and melting of the material at the point of joining. The source of heat is the welding arc. Welding takes place in a gas shielding, which has a direct impact on the efficiency and quality of welding.
What is Welding? - Types of Welding Processes - Bright …
However, fusion welding processes, such as gas welding, arc welding, and gas metal arc welding are used in a large nuer of industries. Gas welding is a process by which the two pieces of metal are locally heated to beyond their melting point, at which time they effectively become one piece of metal.
