Abstract
A bulldozer blade comprises a push plate having a cutting edge mounted on a lower end thereof and a plurality of structural members secured on the back of the push plate and welded together to increase the structural integrity thereof. Each adjacent pair of such members are joined together at a weldment comprising a groove and contiguous dam formed on a surface of one member to have a corner of the other member disposed adjacent thereto and common weld means at least substantially filling the groove and securing the members together. The groove and dam are preformed on an arcuate portion of the first member during a cold forming operation.
