1. What is the difference between stainless steel cold welding machine and argon arc welding machine
1. What is stainless steel cold welding machine
Stainless steel cold welding machine is a cold welding machine, which is often used for welding stainless steel sheets. It releases the electric energy stored in the capacitor between the tungsten electrode and the workpiece in the form of a pulse arc in an instant. The extremely high temperature arc makes the metal The workpiece and welding wire composed of materials are rapidly melted and welded together to achieve the purpose of welding.
2. Introduction of argon arc welding machine
The argon arc welding machine uses argon gas to protect the metal welding material, and the welding material is It is a kind of welding equipment that melts the base material to be welded into a liquid state to form a molten pool, so that the metal to be welded and the welding material achieve a metallurgical combination.
3. The difference between cold welding machine and argon arc welding machine
(1) Welding temperature is different: the welding temperature of cold welding machine is higher than that of argon arc welding machine. The machine is about two-thirds lower, and the temperature of the base metal after welding is only tens of degrees, which can be touched by hand.
(2) The amount of deformation is different: the welding time of the cold welding machine can be precisely controlled, and the welding temperature is much lower than that of the argon arc welding machine, so it has a great advantage in thin plate welding compared with the argon arc welding machine. The amount of deformation is small.
(3) Brightness of weld bead is different: the weld bead of stainless steel cold welding machine is white and bright, and it will not turn yellow and black after welding like argon arc welding machine.
(4) The welding effect is different: the welding bead of the cold welding machine is smooth and white after welding, and the post-welding treatment is simple and convenient, which can be comparable to the welding effect of the high-end laser machine, and will not weld like the argon arc welding machine. The weld bead of the rear solder joint is seriously blackened and difficult to polish.
(5) The ease of use is different: all welding parameters of the cold welding machine are controlled by the welding machine microcomputer, the solder joints are uniform and beautiful, and the operation is simple, no need for professional welders to operate, and those who have no operating experience after simple practice That is, a good effect can be obtained by welding.
2. Who is better between cold welding machine and argon arc welding machine
Compared with cold welding machine and argon arc welding machine, each has its own advantages. Disadvantages, in general, they have their own scope of application. Cold welding machines are more suitable for products with high welding precision and aesthetic requirements, but the efficiency is not very high; if the products are rough and do not require much, If only efficiency is needed, a TIG welder is a better choice.
To sum up, which one is better between cold welding machine and argon arc welding machine depends on the field of use and welding needs. In addition, cold welding machine and argon arc welding machine are not in conflict. Can also be used in combination.
