resistance arc welding requires sufficient
Arc welding protection is one thing that no intelligent welder should overlook. At times when the
things go wrong, it might cause serious consequences, such as severe damages and even death.
Arc welding is in diverse forms such as arc resistance welding ( visit here ), metal arc and gas
shielded. All these different types of welding can actually result in a major injury if appropriate
safety measures are not adopted.
Aspects to consider to ensure safety
There are quite a few general safety tips that should be strictly followed when you are going for
arc resistance welding. Before you resume your work, ensure that you do a proper inspection of
the equipment that you intend to use. Verify few things like frayed wires or the amount of water on
the equipment. Carefully read all the instruction manuals and caution labels that concern your
Always keep a fire extinguisher close by, just in case there is an emergency. Ensure that all the
machines are equipped with the welding machines that are outfitted with power cut off switches,
which you can switch off whenever you make new repairs. Everything needs to be appropriately
Every electrode holder which has defective jaws, loose wire connections, or unfortunate insulation
should not be used. You also need to smack an arc if any person with no eye protection is close
Evolution and working of resistance arc welding
Resistance welding came into existence at nearly the same time as arc welding and also has the
same base that is electricity. In the case of resistance welding, the sheets of metals are placed on
top of each other and the spot that needs to be welded is hard-pressed amid two electrodes. As
the electrical energy moves go on from one electrode to another across the metal, it is temporarily
stopped up by the small gap flanked by the two portions of metal.
Arc Resistance welding works on almost the same principle apart from the fact that the electrodes
are steering wheels and the current in that is driven out in short spurts, which makes a chain of
welds all along the joint.
Different forms used for the process of resistance welding
Resistance Spot Welding, Projection Welding, Resistance Seam Welding Projection Welding (
visit here ) is normally put into use in resistance welding processes. In this it makes use of
application like an electric current and motorized pressure to generate a weld that joins two
separate pieces of metal.
Whereas in the arc welding, the strong heat required to melt metal is shaped by an electric arc.
The arc is fashioned between the real work and an electrode chain or wire that is physically or
automatically guided alongside the joint. In this case the electrode can both be a rod and can
simply carry the current connecting the tip and the work. This can also be specially equipped with
rod or wire which can only carry out the current but also soften and supply filler metal to the joint
that is present. The majority of the welding in the creation of steel products makes use of the
subsequent type of electrode.
