High Frequency Welding ERW Steel Tube Mill HG273

The HG273 straight seam welded pipe unit is a key process in the production of welded pipes. Due to systematic influence factors, we still need to explore experience in the production line. Each unit has its design and manufacturing differences, and each operator is also different. Habits, that is to say, crews, like people, have their own personalities.

Common problems and causes of HG273 straight seam welded pipe unit, solutions:

《1》Welding is not strong, desoldering, cold stacking;

Reason: output power and pressure are too small;

Solution: 1. Adjust the power; 2. Change the shape of the groove for the thick tube blank; 3. Adjust the extrusion force


《2》There are ripples on both sides of the weld;

Reason: the meeting angle is too large,

Solution: 1. Adjust the position of the guide roller; 2. Adjust the solid bending section; 3. Increase the welding speed


《3》Welds have deep pits and pinholes;

Reason: overheated

Solution: 1. Adjust the position of the guide roller to increase the meeting angle; 2. Adjust the power; 3. Increase the welding speed


"4" weld burr is too high;

Reason: The heat-affected zone is too wide

Solution: 1 increase the welding speed; 2 adjust the power;


"5" slag inclusion;

Reason: input power is too large, welding speed is too slow

Solution: 1. Adjust the power; 2. Increase the welding speed


《6》Cracks outside the weld;

Reason: The quality of the base material is not good; too much extrusion force

Solution: 1. Guarantee the material; 2. Adjust the extrusion force


《7》Wrong welding, lap welding

Reason: Poor molding precision;

Solution: Adjust the forming die roller of the unit;


The HG273 straight seam welded pipe unit is a key process in the production of welded pipes. Due to systematic influence factors, we still need to explore experience in the production line. Each unit has its design and manufacturing differences, and each operator is also different. Habits, that is to say, crews, like people, have their own personalities. We provide these materials to everyone so that we can better understand the basic principles of high-frequency welding, and thus effectively combine our own production practices to sum up the operating procedures suitable for our own units.


The formula for calculating the steel strip width of HG273 straight seam welded pipe unit equipment:

B=pi*(D-t)+b1+b2+b3

B Strip width

t Formed steel pipe wall thickness

b1 molding allowance

b2 welding allowance

b3 sizing allowance
