The advent of rolling mill technology and its development during the first half of the nineteenth century also heralded in the industrial manufacture of tube and pipe. Initially, rolled strips of sheet were formed into a circular cross section by funnel arrangements or rolls, and then butt or lap welded in the same heat (forge welding process).
Oct 04, 2018· Cracks, for example, require complete removal. There are shops willing to repair weld teeth, and while I salute them for their patience and artistry, I do not want to be associated with the results. If you weld anything, even far away from the gear teeth, you have to do a thorough check for cracks following the postweld stress relief.
