What are the main differences between spot welding head and soldering iron head

Spot welding heads are generally used in spot resistance welding equipment , and are in direct contact with the object to be welded, which is the equipment that directly supplies current and pressure to the object to be welded.

The main difference between spot welding head and welding head is:

Spot welding is actually a kind of electric welding. The object to be welded is dissolved on another object to be welded in contact with the object to be welded by the instant high temperature of the current, and then welded together. The electric soldering iron is a hand-soldering tool, and the soldering iron tip is heated to a temperature above 300℃ to be able to perform soldering well.

When selecting spot welding heads, you can also choose from these aspects:

1.Select the spot welding head data and spot welding head type mainly based on the welding wire data and the melting point of the pad data.

2.According to the requirements of the soldering joints, select the contact area of the discharge part of the spot welding head with the weldment. Large welding wires require a large contact area.

3.Select the shape of the discharge part according to the welding wire data and welding data.

4.Set the shape of the current collecting part of the welding head according to the principle of better discharge.

However, it should be noted that it is not possible to perform dry welding, that is, discharge operation without touching any metal. The spot welding head will head high temperature of thousands of degrees during discharge. If there is no contact with any metal body, the spot welding head will be at high temperature for a long time, because it is easy to form oxidation when air is in contact, and a black oxide layer will occur. Then lower the welding head. Long service life and reduced welding welding effect. The discharge part of the spot welding head prevents the adhesion of conductive foreign matter in the cavity. If the conductive foreign matter is adhered, the welding effect will be reduced.

Through many years of independent research and development, our company specializes in the production of various rare metal products such as fine hot-pressed spot welding heads, pulse hot-pressed spot welding heads, tungsten boats, molybdenum boats and tungsten-molybdenum-titanium alloys. Products are now widely used in non-standard equipment such as Japanese special welders, sensitive spot welders, hot presses, etc. The spot welding head produced the company has the advantages of stable quality, fast thermal response time, uniform welding, non-sticking tin, beautiful welding surface, and long life. Our products are imported from imported materials, independently produced and customized, which can satisfy customers.
