18/12/2015· In the welding world, newcomers often find themselves lost in the common phrases and slang words thrown around by their fellow workers. Here is the ultimate guide on welding slang in the workforce. You will find the egories in these subjects: People; Equipment
Electric Arc Welding: Meaning, Procedure and Equipments
The arc welding is a fusion welding process in which the heat required to fuse the metal is obtained from an electric arc between the base metal and an electrode. The electric arc is produced when two conductors are touches together and then separated by a small gap of 2 to 4 mm, such that the current continues to flow, through the air.
MIG Welding Tips and Techniques for Beginners
10/6/2019· Pulling the trigger electrically energizes the welding wire and starts the motor drive, feeding the wire automatically as you weld. MIG welding requires the weld to be shielded from the atmosphere. This is often done by directing shielding gas over the weld area — and the flow of gas is also controlled by the trigger on the gun.
Fabriion-welding : 2014
SMAW- It stand for shielded metal arc welding , an arc welding process in which joining takes place between the tip of covered electrode and the surface of the base metal Shielded Metal Arc Welding (SMAW) or Stick welding is a process which melts and joins metals by heating them with an arc between a coated metal electrode and the work piece.

Tips For Avoiding Common Flux-Cored Problems & …
If using a weaving technique, momentarily hold the arc on the groove sidewalls when welding. Increase your voltage range and/or adjust the wire feed speed as necessary to obtain complete fusion. Also, if you feel that the wire is getting ahead of the work puddle, simple adjustments, such as increasing travel speed or using a higher welding current, can prevent problems.
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
