Common problems of tank welding machine.
l Why is the tank welding machine suitable for welding thin plates and drawn arc welding for thick plates?
1. In most cases, tank welding machine is suitable for welding on thin plates, and drawn arc stud welding is suitable for welding on thick plates.
2. Tank welding machine is characterized by high current and short time, so the molten pool is shallow and welding deformation is small.
3. But at this time, the welding strength is still relatively large (welding strength> stud strength> sheet strength, or welding strength> sheet strength> stud strength). Therefore, it is the stud or the sheet that yields first.
4. If tank welding machine is used on a thick plate, the strength of the plate itself is the greatest, because it is almost impossible to be torn, so the stud or welded joint may yield first.
5. Another reason is that tank welding machine cannot be welded on hot-rolled plates, and thick plates are hot-rolled plates in most cases.
6. The drawn arc stud welding current is relatively small, but the welding time is longer, so the molten pool is deeper and the welding deformation is larger.
7. If the deeper molten pool is welded with thin plates, it is easy to cause penetration. Generally, the mminimu plate thickness is required to be 1/4 of the stud diameter.
8. The deeper molten pool makes the welding strength always greater than the strength of the stud itself, so the stud or plate is always the first to yield in the destructive experiment.
l In the stud welder test, how to understand "the welding strength is greater than the strength of the plate and the stud itself"?
1. This sentence is mainly aimed at tank welding machine welding strength test.
2. In the destructive experiment, if the plate is torn or pulled through, and the stud welding part is still not separated from the plate, it means that the stud welding strength is greater than the strength of the plate itself.
3. If the stud is broken or bent and the welded part of the stud is still not separated from the plate, it means that the strength of the stud welding is greater than the strength of the stud itself.
What are the correct operating specifications for tank welding machine work?
l 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:
There must not be any leakage of cooling water, shielding gas or engine oil that affects the safety of welders.
l Work suspension
When the welding work is suspended (for example, during breaks), the output terminal of the equipment or welding machine must be turned off or the power supply must be cut off.
l Mobile welding machine
When you need to move the tank welding machine, you must first cut off the power supply at its input end.
l 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 tank welding machine must be properly placed when not in use to avoid accidental activation of the gun body switch.
All arc welding equipment must be maintained at any time and kept in a safe worki

Advanced tank jacking system (package unit) is evenly distributed around tank inner wall. Tank top and upper (the first layer) wall plates are lifted first and then install and weld wall plates of tank body. Self locking advanced tank jacking system and hydraulic hoist composing of lifting frame and lifting rod are adopted. When oil enters advanced tank jacking system, upper clamp fastens and lifts lifting rod and expansion ring and mobilize tank (including tank top) to ascend upward. When oil returns to jack, upper clamp returns with piston and lower clamp automatically fastens lifting rod without gliding. The jack repeats the movement and make lifting rod ascend with tank to designated height (spare height for next layer of plate). After butt weld of next layer of wall plates, open upper and lower loosening device and loosen upper and lower clamp to make lifting rod and expansion ring descend to lower expanded and welded rib plate of the next layer of wall plates and then lift. Repeat the process and ascend welded tan till the last layer of wall plates are installed and welded. The installation of the whole storage tank is completed.
