چکیده
This study aimed to analyze BKI Grade (KI-A) plate material using the pre-heat process determine tensile strength and hardness. The method involved welding with shielded metal arc (SMAW) type. variations used several temperatures, such as 50⁰C, 120⁰C, 220⁰C, without heat treatment. obtained specimen pre-heating had lowest of 442.64 MPa, 220⁰C highest average 450.11 MPa. result showed that was proportional temperatures given. hardness observation found hotter temperature obtained, higher value base HAZ would obtain. It different weld which decrease. From those two parameters, it could be concluded most optimal 220⁰C.

Robotic Shielded Metal Arc Welding
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 ...
