Purpose and ScopeThe purpose of this lab report was to learn basic welding and shop safety practices to successfully gain experience in MIG (semi-automatic) welding techniques and electrode (manual). The overall purpose of this lab report was to gain exposure to weld inspection and destructive testing by overloading prepared weld samples and analyzing them. Experimental Procedure The procedure in this lab report involves welding two small sheets of metal (each relatively 3x6 inches) together using both MIG methods and stick welding techniques, then cutting the welded piece to produce two specimens. Of the two samples one would be MIG welding and the other sample would be stick welding. Using a loading machine, the samples were loaded to failure and the destructive test results were analyzed. To prepare for the nature of this lab report, Thomas Hatch and Lucas Jones presented a shop floor lab overview and two welding demonstrations. who are two of Penn State Altoona's lab supervisors. The lab overview provided solid mechanical information on horizontal and vertical saws, belt sander and wheel grinder, as well as MIG and stick welders. Safety practices and procedures for each of the above-mentioned machines and welding machines were also covered. Two welding methods have been demonstrated; one was MIG welding and the other was stick welding. Proper technique, form and safety were highlighted as three important factors of welding. Technique will provide precision, form will provide accuracy, and confidence will provide repetition. Before welding and cutting the specimens needed for this lab, a summary of the lab safety rules, from the PSU Altoona Lab Safety Rules and Chapter 4 of Modern Welding Technology 6th Edition, was completed. At the stern...... in the center of the sheet ......steered by many people. Electrode welding is a very mobile and useful welding because the electrode coating acts as a shield during welding and coats the top of the weld with slag which is resistant material. Concluding the results, to improve electrode welding, it is important ((to think about welding speed. It is necessary to compensate for the decrease in stick length at a speed that keeps the arc constant to produce the right amount of heat needed for deep penetration to keep the weld closed. For the MIG welder, it is important to maintain the proper speed and understand the geometry of the An adequate groove width and pool size, combined with the speed of operation, will produce a solid weld Keep in mind that sanding and grinding are an important step in welding. Modifying the weld surface can be very helpful in completing a strong, long-lasting weld. References
