Can The Bolt Ball Space Frame Structure Be Welding

It can be sure that the bolt ball can be welded, like the support of bolt ball space frame structure is welded.

The material of bolt ball is made of 45# steel, which is similar to the material of Q235. The electrode should be E43XX low-hydrogen electrode during welding. The electrode should be dried before use and keep warm during use. The weldment should be preheated before welding and kept warm after welding. As long as the the process sequence is correct, there is no problem with welding itself. But the welding will cause a series of problem that restrict the feasibility of welding.

1. The bolt ball is a solid core ball. Even if it’s preheated, the temperature is much different from the temperature during welding(the preheated temperature can not be too high),The local heating stress may further expand the cracks formed during the forging process of the bolt ball. , Has an adverse effect on the force and anti-corrosion.
2. The bolt ball space frameis smaller then the weld ball space frame. In order to ensure that the steel bar do not affect each other, the thicker steel bar are equipped with cones and bolts to connect with the ball. If it’s changed to welding, it will inevitably affect the connection of other steel bar.

There is a space frame installed company said that , due to the processing errors of space frame bolt ball is a small factory, one hole was missing, but part of the steel bar have been assembled, and the construction period is very tight, so they ask for help weather the bolt ball can be welded on site.

My suggestion is to reprocess a ball or drill a hole , so that the problem will be less. If the ball has been installed,whether it is welded or replaced, it must be removed, If it’s removed for welding, first of all, it’s difficult to preheat and heat preservation, and other high-strength bolts which connected to the ball will be affected.

Therefore,the professional of the space frame structure company is very important.When it come to the professional, you can consult me about any question on the space frame, I will help to solve the problem.
