Manual Metal Arc Welding (MMA, SMAW or Stick …

Job Knowledge 2 Manual metal arc welding (MMA or MMAW), also known as shielded metal arc welding (SMAW), flux shielded arc welding or stick welding, is a process where the arc is struck between an electrode flux coated metal rod and the work piece. Both

Weave VS Stringers VS manipulating the electrode

Weave VS Stringers VS manipulating the electrode (My opinion) When I weld in the vertical position with GMAW or FCAW I have to manipulate the electrode. Even if I am making a 3/16" fillet. This manipulation reduces the convexity of the bead by spreading the

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

The Common Welding Methods - Pros and Cons

Stick welding is another name for shielded metal arc welding or SMAW. This type of welding is used for welding almost all the ferrous metals and also other metal types, using special electrode. In this process, a welding rod or electrode, consisting of a flux coated core wire, is used to carry the current, providing the majority of the metal weld.

Low Heat Input SMAW Welding Electrodes

do not weave the electrode. Use stringer bead technique. If weaving becomes necessary due to position of welding, the width of weaving should not exceed two to three times the core wire diameter of the electrode. • While welding on austenitic manganese steel
