Welding By The Numbers
Dr. Joe Maj, AirVenture volunteer in the Gas welding workshops and SportAir Workshop instructor shares his three key numbers for gas welding success. If you adopt these three key numbers, you will learn to gas weld much quicker and easier.
Tube Coping with Angle Grinder
EAA Technical Aviation Expert Tim Hoversten demonstrates the use of an inexpensive angle grinder with a 60 grit flap disc to shape steel tubing when fitting joints for welding.
Welding Helmets Overview
Not all welding helmets are the same. Charlie Becker from the EAA staff reviews the basic and some special features of helmets and discusses how more than one helmet is useful when welding aircraft structures.
Marking Tubing Reference Lines
Timm Bogenhagen from the EAA staff demonstrates an easy way to mark a reference line on long pieces of tubing.
Joining tubes together requires shaping the tube end to get a good tight fit. Charlie Becker demonstrates a technique he learned from Paul Poberezny to fishmouth tubing for good tight fits.
Gas Welding Tip Selection
A lot of begining welders ask what size welding tip do I need to weld steel tubing? Dr. Joe Maj, AirVenture volunteer in the Gas welding workshops and SportAir Workshop instructor, answers this confusing question.
Modified Seine Knot - Alternate Method
Jasen Golden from Rainbow Aviation Services demonstrates an alternate sequence to tie the modified seine knot for rib stitching fabric covered aircraft.
