The butt welding machine uses the resistance heat energy between the sections of the butt welding machine to melt and fuse directly. The electric welding machine does not use the resistance between the contact surfaces of the butt welding machine to generate heat, but uses the high-temperature arc generated by the positive and negative electrodes of the welding machine in the instant short circuit to melt the welding electrode and the welded material, so as to combine the contacted objects.
What are the operating points of the butt welding machine?
What are the point that we should notice when using the butt welding machine?
How to choose electric welding machine and butt welding machine?
Operators of the butt welding machine must undergo professional training, be familiar with the structure, performance, and operating procedures of the butt welding machine, and master the knowledge of process parameter selection and quality inspection specifications.
Before operation, check whether the various mechanisms of the butt welder are sensitive and reliable, whether the electrical system is safe, whether the cooling water pump system is leaking.
It is strictly forbidden to butt welding steel bars with a diameter exceeding the specified diameter. The butt welding of the main steel bars must be welded first and then cold drawn. In order to ensure the welding quality, the welding machine should be cleaned, rusted and corrected within the range of about 150mm from the felt end.
Operators must wear colored protective glasses and hats when using the butt welding machine to prevent arc light from irritating the eyes and melting metal to burn the skin.
The butt welding machine is needed to be parked in a clean, dry and ventilated place. The butt welding machine used on site should be equipped with rainproof, moisture-proof, sun-proof shed, and equipped with fire-fighting equipment. No flammable materials should be stacked in the welding area.
When using the butt welding machine, we need to equip it with a dedicated wiring switch and installed in the switch box. Since the capacity of the fuse should be 1.5 times the capacity of the machine. The shell of the welder must be well grounded.
After butt-welding visual inspection, the steel joints should be properly upset, and there should be no cracks and obvious burns on the surface. The crankshaft of the joint axis is not more than 6°, and it is not more than 1/10 of the diameter of the steel bar, and not more than 2mm.
The electric welding machine adopts the secondary side relatively high voltage (above 60V) and the larger current uses welding rod as the electric welding material to start arc welding; while the butt welding machine adopts the secondary side low voltage (below 10V) and the high current is 2 Metal parts generate arc self-fusion welding with electricity, or the upper and lower welding heads press two pieces of iron into contact with high current self-fusion welding.
This is how we see the irreplaceable role of butt welding machine in our daily lives and industrial production. WELPING, the pioneer of butt welding machine producing company in China, knows that every application is special. You can go and get more information about them.
