The intermediate frequency DC spot welding machine should be provided with reliable grounding protection. The parallel installation distance of multiple equipment should not be less than 3m. It should be checked before operation. The pressure mechanism of the welding machine should be flexible, the fixture should be firm, and the gas-liquid system should not leak.

Before welding, adjust the corresponding parameters according to the workpiece to be welded. The secondary voltage should be discharged regularly, the contact points and electrodes of the circuit breaker should be polished, and all the connecting bolts of the secondary circuit should be tightened regularly.

Regularly inject lubricating oil into the rotating conductive parts. The maintenance of the welding arm and electrode is that a large current will pass through the welding arm and electrode when it is working. If the surface accumulates a thick oxide layer, it will cause poor resistance contact, which will eventually lead to unsightly solder joints. .

Before welding, it mainly finds suitable welding conditions at the beginning, and adjusts the suitable parameters according to the workpiece to be welded, then the control device (that is, the controller) will perform welding according to the set conditions, in order to find good welding conditions Requires people who are familiar with welding technology, but after setting good welding conditions, even workers without operating experience can operate it.

But one thing worthy of our attention and learning is that during the operation, the surface of the electrode will form a white medium on its surface as the number of welding increases. If it is not ground in time, it will increase the resistance and affect the quality of the solder joints. In order to guarantee the welding quality at all times, a file or electrode dresser should be used for grinding regularly.

During spot welding, there is a set of standard welding condition tables for mild steel, stainless steel, and aluminum alloy materials. After actual operation according to the welding condition table, if there is a problem with the nugget diameter or welding strength, then Modify the set value before and after this value to find out the welding conditions.

　 　 　 But if it is the same type of metal, it is also necessary to continuously improve the welding conditions according to its plate thickness, surface condition and target size of the nugget diameter of the joint, surface condition after welding and other requirements.

But the most important thing to pay attention to is safety first!

First of all, a high-quality intermediate frequency spot welding machine, its transformer must first be wound with copper enameled wire, and secondly be an integrated water-cooled structure casted with copper. The high-quality oxygen-free copper structure has good effect, low resistivity, high conductivity, slow oxidation speed and long service life. In recent years, more and more vacuum cast transformers have become a trend, because vacuum cast transformers are moisture-proof. The heat effect is good and the service life is longer.

Packing used for butt welding machine

Butt welding machines belong to the mechanical category, with relatively large volume and heavy weight, and strict packaging requirements. Solid wood boxes are generally used for packaging, and plywood boxes that meet international standards must be used for export.

There are many methods of metal welding. How to find the most suitable welding method for you, I believe that everyone is very astute, and will consider all aspects of cost, efficiency, product quality, quality of welded products, mechanical life, environmental protection, etc., these editors I won't write it specifically for the time being, let's talk about the basic method first.

1. In terms of broad categories, there are three methods:

1. Pressure welding
2. Fusion welding
3. Brazing

1) Pressure welding is subdivided into:

①　 Resistance butt welding
② Resistance spot welding, projection welding, seam welding
③　Cold welding
④　Ultrasonic welding
⑤　Explosive welding
⑥　Forge welding
⑦　Diffusion welding

2) Fusion welding can be subdivided into:

① Arc welding: plasma arc welding, atomic hydrogen welding, argon arc welding, gas shielded welding, submerged arc welding, stud welding, electrode welding.
② Gas welding: oxygen hydrogen gas welding, oxygen acetylene gas welding, air acetylene gas welding.
③　Thermite welding
④　Electroslag welding
⑤　Electron beam welding
⑥　Laser welding


3) Brazing can be subdivided into:

①　Flame brazing
②　Induction brazing
③　 brazing in the furnace
④　Salt bath brazing
⑤　 electron beam brazing
