ME 477 Lecture Notes - Lecture 6: Friction Stir Welding, Arc Welding, Fastener
Document Summary
Homework #6 me 477: list the advantages and disadvantages of mechanical fastening as compared with adhesive bonding. High exposure can be bad in corrosive environments. Higher cost than adhesive bonding (cid:12254) (cid:12254) (cid:12254) (cid:12254) (cid:12254) (cid:12254) (cid:12254) (cid:12254) (cid:12254: explain the factors involved in electrode selection in arc welding processes. Surface finish - a non-consumable electrode can be chosen if a high quality and good surface nish are required. Quality - a deoxidizer must be present in the electrode chosen if preventing oxidation is required. High heat - the selection of tungsten electrodes are chosen if high temperatures are desirable. Consumable electrodes have signi cant changes in their structure when used. Non-consumable electrodes are not consumed during the welding process. Both are used to weld two materials together: what advantages does friction welding have over the other joining methods. The advantage of friction welding is that similar metals can be welded together.
