Notes:
This work studies the behaviour of welding joints under abrasive wear in A355 Gr. P11steel pipes carrying liquids at high temperatures. Various welding processes were tested on differentjoints in an effort to choose the one that gave the best wear response. For this purpose, a pin-on-disktribometer was used at 200ºC to simulate the service conditions of the pipes.The tests were carried out by pressing a hard chromium-plated steel pin, with a diameter of 4 mmand hardness of about 775 HV, on steel specimens in order to measure their mass loss and frictioncoefficient in the three welding zones: base metal (BM), heat affected zone (HAZ) and weld bead(WB). The tests conditions were 10 N of load, 200 rpm of rotation velocity and a radius of 3 mm. Inaddition, metallographic studies and hardness measurements of the three welding zones were doneto complete this work
