Friends, all welcome. Today, we will once again be a useful topic for everyone who decided on their own to master manual arc welding. And talk about as a gash proftrubu for docking to cook a very strong connection. Besides, this way I've been doing in practice many times, and it all the test of time and stress.
Sometimes I have to repair the rusty rail to trucks. Usually the trucks transporting bulk cx culture rot bottoms sides. Therefore it is necessary to remove the rusty areas and on their spot weld the new.
Therefore, a new section proftruby such boards need to weld and join in such a way as to obtain maximum durable connection.
Based on the increased requirements for structural strength I zapilivaem proftrubu for docking at 45 degrees.
The main thing here all good measure, that when you failed to adjust the new pipe with gashes of 45 degrees were slightly longer or shorter than normal, otherwise it does not, and clearances from the side uprights and a base change, which is not desirable.
When everything is well fitted and is stuck, first brewed internal and external seams, and then face-when viewed straight on board.
Naturally, during the assembly, tack welding and we constantly monitor that new welded parts were a direct continuation of the old pipes, so as not filled up to the side, and were exactly right.
This method, I started to apply for a long time to repair the boards, and so in his village has been renovated many units of trucks. No complaints or complaints about the weakness of the construction has not been repaired, many boards often catch the eye, technology is constantly at work.
Therefore, I recommend this method of docking proftruby if this design will take any load if the individual will not load, you should not be exhausted with this, the junction ends just under 90 degrees.
