A mild route for the preparation of calcium carbonate rod bundles in large scale from carbide slag 1 INTRODUCTION Industrial solid waste has cascaded detriments on the envi-ronment and further sustainable development of mankind, due to the high output and the difculty of treatment. Car-bide slag, as one of the industrial solid wastes on a large
Thus, the correct size of electrode for the joint preparation, the correct angle to the workpiece for good penetration and a smooth weld bead profile are all essential to prevent slag entrainment. In multi-pass vertical welding, especially with basic electrodes, care must be taken to fuse out any remaining minor slag pockets and minimise undercut.
