Jichangdi brand hot melt welding can mainly weld pure copper, brass, bronze, red copper, copper clad steel, pure iron, stainless steel, wrought iron, galvanized steel, cast iron, copper alloy, alloy steel and other metal materials.

There are 8 types of hot-melt welding, wire and wire welding, wire and metal row (belt) welding, wire and ground rod (pole) welding, wire and metal plate are very connected, metal row (belt) and metal row (belt) Welding, metal row (belt) and ground rod (pole) welding, metal row (belt) and metal plate welding, metal rod and metal plate welding.

Each type of welding also includes different connection methods, such as butt connection, cross connection, parallel connection, T-shaped connection, etc. in the wire welding. Various forms can complete good welding.

It is widely used in power plants, substations, transmission line towers, communication base stations, airports, railways, various high-rise buildings, microwave relay stations, network computer rooms, petrochemical plants, oil storage depots, etc. lightning protection grounding, anti-static grounding, protective grounding, work Welding for grounding etc.

Applications

1. Horizontal ground connection

2. The signal line is connected to the oil and gas pipeline

3. The signal line is connected to the rail

4. Connection with steel bars

5. Connection of lead wire and terminal

6. Other electrical connections

Precautions

1. First, according to the shape and size of the connecting piece, open a suitable mold, and configure the corresponding type of solder powder

2. Treat the drawing parts before welding, remove oil, dirt and oxide layer

3. Fully heat the mold

4. After installing the mold, pour the solder powder and ignite the reaction

5. Clean the mold and prepare for next use

Hot welding process

Preparation and key points of mold and mold clamp

1. Dry the mold with a heating tool (such as a drying box or a blowtorch) before use to remove moisture. Molds that have not been used for a long time contain moisture, especially molds with residue left after the previous use.

2. To clean the mold, please use a soft brush or other soft material.

3. Check the tightness of the mold contact surface to prevent copper liquid from leaking out of the gap during operation.

4. The mold clamp is used to open and close the mold. The tightness of the mold clamp has an impact on the welding effect. Please check the mold clamp carefully and make appropriate adjustments before the welding starts.

5. Install and adjust the mold clamp to adjust the tightness of the mold clamp and the tightness of the mold to a better state. The adjustment method is as follows:

a) Put the mold clamp in the open state or position

b) Loosen the mold clamp fixing latch (1)

c) Take out the fixing bolt (2)

d) Adjust the adjusting screw (3) to rotate counterclockwise (loose)

e) Insert the fixing bolt and lock

f) Open and close the mold clamp and observe the effect.

Repeat the adjustment of the clamping distance in this way until the tightness of the mold clamp matches the tightness of the mold. If the opening and closing of the mold clamp requires greater force, it means that the clamp distance has not been adjusted to a better position (the clamp distance is too short) and needs to be adjusted again. The installation and adjustment of the mold clamp has an important influence on the welding quality of "hot welding" and the service life of the mold and the mold clamp, so please adjust the distance carefully before welding. Regardless of whether there is a weld in the mold, improper clamping distance will cause damage to the mold and the mold clamp.

(1) Fixed bolt lock

(2) Fixing bolt

(3) Adjusting screw

6. The Jichangdi brand exothermic welding mold is made of graphite, which is very fragile and cannot withstand throwing and force impact. Therefore, it is not allowed to force the welded material beyond the size shown on the mold nameplate into the mold, or use metal or hard tools. Wait to remove the residue.

7. If the size of the welded object is smaller than the mold nameplate, in order to avoid the leakage of copper liquid, the following methods can be used to make up: (picture)

1) Use sealant

2) Use high temperature cotton tape

8. If the graphite mold is maintained according to the above steps, the service life can reach more than 50-100 times.
