These instructions often include which type of weld to be used, the size of the weld, how many similar welds need to be performed, and tell the welder which joint the weld should be made. You will go over the basic lines which includes object line, hidden lines, center lines, extension lines, dimension lines, leader lines, cutting plane lines, section lines, short break lines, long break lines and phantom lines. Reading welding blueprints can be very complicated and confusing on occasions. But after you have gained some experience in reading blueprints it will become second nature. As with all welding techniques, with some time and practice you will soon began to master the processes.
