The development of technology is increasing rapidly in the field machine construction desperate need connection techniques between interconnected parts construction. This study aims to compare method electrode movement direction using commercial steel value distortion and hardness. uses seam V with an angle 600 a current 100 amperes. used E 6013 diameter 3.2 mm test object has thickness 10 leng...

-Hardfacing is one of the most useful and economic ways to improve the performance of components submitted to severe wear conditions. A study was made to compare the microstructure and abrasion resistance of hardfacing alloys reinforced with primary chromium carbides, the hardfacing alloys were deposited onto M.S. plate by SMAW process. Two different commercial hardfacing electrodes were employ...

The objective of this study was to characterize personal exposures to welding-related metals and gases for production welders and non-welders in a large manufacturing facility. Welding fume metals and irritant gases nitrogen dioxide (NO2) and ozone (O3) were sampled for thirty-eight workers. Personal exposure air samples for welding fume metals were collected on 37 mm open face cassettes and ni...

In this work, the development and validation of a methodology for robotic welding with covered electrodes (SMAW) using a variation of the tool center point (TCP) model is shown. The covered electrode becomes part of the kinematic model of the robot as an additional prismatic joint, whose movement is determined by the electrode consumption or melting rate. This allows programming the trajectory ...

Pengelasan marupakan metode penyambungan material yang sering digunakan pada kapal dan industri lepas pantai. Baja karbon rendah seperti baja A36 structural steel 400 (SS400) merupakan dalam konstruksi kapal. Pada penelitian ini akan dilakukan analisis pengaruh variasi heat input pengelasan SMAW sambungan pelat dengan terhadap uji laju korosi beberapa sifat mekanik impact metalografi. Untuk ada...
