Precautions for tank welding machine.

The tank welding machine uses electrical energy to instantly convert electrical energy into heat. The tank welding machine is suitable for working in a dry environment without too many requirements. Because of its compact size, simple operation, convenient use and fast speed. Next, we will introduce the precautions of tank welding machine.

Introduction to the advantages and disadvantages of tank welding machine.

The advantages of tank welding machine after welding are widely used in various fields, especially for parts that require high strength. It can instantly connect the same metal material (also can connect dissimilar metals, but the welding method is different) permanently. After heat treatment, the weld seam has the same strength as the base material and is well sealed, which solves the problems of sealing and strength for the manufacture of storage gas and liquid containers.

 

However, when the tank welding machine is in use, a certain magnetic field will be generated around the welding machine. When the arc burns, radiation will be generated to the surroundings. The arc light contains infrared rays, ultraviolet rays and other light species, as well as metal vapor and smoke and other harmful substances. Adequate protective measures must be done at the time.

 

Welding is not suitable for high-carbon steel welding. Due to the process of crystallization, segregation and oxidation of weld metal, the welding performance of high-carbon steel is poor, and it is easy to crack after welding, resulting in hot and cold cracks. Low carbon steel has good welding performance, but the process must be handled properly. Derusting and cleaning are more cumbersome. Sometimes the weld will have defects such as slag inclusion, cracks, pores and undercuts, but proper operation will reduce the occurrence of defects.

 

Matters needing attention when cleaning tank welding machine.

When cleaning the tank welding machine, it is necessary to grind the inner and outer burrs of the tube end to make the tube end flush without burrs, and wipe it clean with alcohol. Manual tungsten argon arc welding is used for positioning, and the location of the positioning solder joints should not be too high, the current should not be too large, and the penetration is not allowed, the number of solder joints should not be less than 2, and the solder joint diameter should not be greater than 6mm.

 

If the position of the tank welding machine is not used properly, the position of the welding point will deviate from the neutral line of the welding butt surface. Due to the regular shape of the girth welding seam, the position welding point that deviates from the welding seam cannot be covered by the normal welding seam, resulting in The positioning welding spot is on the edge and outside of the welding seam, which makes the welding seam surface poorly formed.

 

How to use a tank welding machine?

Check the connection

After completing the wiring of the tank welding machine, you must check each installed connector to confirm that it is well connected before starting to operate the equipment. Its contents include:

1. The line connection is correct and reasonable, and the grounding must meet the specified requirements

2. The magnetic work piece gripper shall not have attached metal particles and splashes on its contact surface;

3. The coiled welding cable should be unrolled before use to avoid overheating and insulation damage;

4. When it is necessary to alternately use different lengths of cables, insulating joints should be provided to ensure that useless lengths can be disconnected when not needed.

leakage

There must not be any leakage of cooling water, shielding gas or engine oil that affects the safety of welders.

Work suspension

When the welding work is suspended (for example, during breaks), the output terminal of the equipment or tank welding machine must be turned off or the power supply must be cut off.

Mobile welding machine

When you need to move the tank welding machine, you must first cut off the power supply at its input end.

Equipment not used

The metal electrode and carbon electrode must be removed from the welding tongs when not in use to eliminate the risk of electric shock to personnel or conductive objects. The welding tongs must be placed out of contact with persons, electrical conductors, flammable objects or compressed air bottles when not in use. The welding torch of the semi-automatic welding machine must be properly placed when not in use to avoid accidental activation of the gun body switch.

maintain

All arc welding equipment must be maintained at any time and kept in a safe worki.
