2 basic types, Gas shielding, and flux shielding. Gas shielding comes from compressed tanks of inert gas such as argon. these gases are pumped through the welding hose and over the weld pool. The flux type protects the weld by covering it in a layer of slag that prevent it from being contaminated by the surrounding air.
Their are many types of welding electrodes. They are grouped according to the matrix used to hold the ingredients and/or the type of metal to be welded. Steel electrodes are classed in 3 types, 1 mild steel, 2 medium tensile steel and 3 hi-tensile steel. Mild steel are used to weld mild steel surprise!! and have a tensile strength of 60,000 psi. +/-. Some types are 6010 - 6011 - 6013 etc. Medium tensile fall into the 70,000 to 80,000 psi range and can be 7016 - 7018 etc. or 8016 - 8018 - 8020 - 8024 etc. High tensile run 90,000 psi. and up. ie: 9018, 10018, 11018, 12018 and have the equvilent tensile strength (psi = pounds per square inch). A CLUE the last number indicates what position you can weld in. Flat, horizontal, vertical up, overhead. 1 = all position 2 = flat and horizontal 3 = flat only 4 = all plus vertical downhand. Their are many types of metal produced from stainless steel to tungsten carbide. Not all can be welded. Some have to be brazed or silver soldered. Charts can be obtained to tell you what electrode or process to use in almost any situation. Or ask your welding supplier.
Welding is a manufacturing method that fuses or unites materials, typically metals or thermoplastics, by melting the component pieces at high heat and allowing them to cool. Welding is distinct from low-temperature processes that melt the base metal, such as brazing and soldering.
15 Types of Welding Equipment and Their Uses
The primary categories of welding equipment used in the welding industry are as follows:
There is,
Gas welding,
Stick or Arc welding,
Mig welding,
Tig welding,
TIG welding,MIG welding,plasma arc welding, ARC welding & laser welding
There are many MANY types of welding processes, but the most common for metal are: Gas-Torch welding, TIG welding, MIG welding, Flux wire welding, and Stick welding.
The three common welding processes are oxyfuel welding, arc welding, and resistance welding.
What es the five essential of
transformer and rectifier machines
I am not sure your question is clear enough but here I go... Stick Arc Welding (AC or DC), MIG (Metal Inert Gas) and TIG (Tunsten Inter Gas). All three of these are the basic metal welding machines.
Mainly In spot welding & resistance welding two type welding machines are used :- 1. Air Cooled & 2. water Cooled.
V= 0.05 i + 10 for mmaw welding v= 0.05 i + 20 for tig welding
There are far more than 5 types or processes of welding. Currently the American Welding Society (AWS) states that there are more than 80 different welding and joining processes. However, some of the common welding processes include shielded metal arc welding (SMAW), gas metal arc welding (GMAW), gas tungsten arc welding (GTAW), flux cored arc welding (FCAW), and oxyfuel gas welding (OFW).
EFW: Electric Fusion Welding is a more general term which includes Electric resistance welding (ERW) and other types of welding such as Arc welding.

Welding machine companies are important, because welding machine manufacturers like Artech Welders, Dynarc Systems, Crystal Electrodynamix are provides all types of welding machines for various business firms.
The new principal inside welding machines is based on metal-arc welding, whereas the older welding machines used electromagnetic winding to increase the current in welding rods.
Mainly In spot welding & resistance welding two type welding machines are used :- 1. Air Cooled & 2. water Cooled.

Who makes the best welding machines is quite subjective. Some of the best machines are said to be made by Lincoln Electric while others prefer Miller Electric machines.

SMAW stands for shielded metal arc welding. The rectifier used in the welding machines must be referring to this type welding.
Depending upon the type of welding machine, its cost varies from Rs50.000 to more than Rs 1,00,000. Manufacturers like Artech welders, Roteckweld offers welding machines at affordable cost.
Welder is a tradesman who specializes in welding materials together. Welding is a process that joins materials. Hobart Welders is a brand of welding machines. And yes, they are good.
