Abstract A36 and A53 steels are low carbon steel with relatively similar percentage, respectively 0,25-0,30% 0,25-0,29%. Both often used within the marine industry. The objective of this research is to figure out effect variation groove angle heat input process welding two different plates towards a metallography, tensile, bending test E71T electrode, as well figuring weld 18 mm thick plates. 5...

Air laut merupakan media korosi yang paling mudah mengkorosi material, terutama baja. Pada industri perkapalan, sebagian besar konstruksi kapal terbuat dari material baja akan kontak langsung dengan air dalam waktu lama. Seringkali terbentuk di permukaan plat, namun pada area sambungan las bisa saja terjadi kecacatan selain dipengaruhi oleh korosi, juga proses pengelasan. Sehingga dilakukan pen...

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 ...

This work presents the procedure qualification for pipeline orbital welding using a robotic system. The system has four degrees of freedom, which allow the controlling of the stick out, the travel speed, the torch angle and the positioning. The arc voltage and welding current are also controlled during the welding, although the system uses a conventional power source. With the system it is poss...
