Weld values for aluminum

Weld values for aluminum

Weld values for aluminum

(OP)
We are used to working with steel.  We have a job using steel and aluminum.  I have two questions:
1.  What is a good basic text book for aluminum design that covers welding of aluminum?

2.  To determine values of aluminum welds, is the equation as follows:
3/16"  - 0.1875*0.707*0.6F/2

What to use for F?

Sincerely

RE: Weld values for aluminum

If you are going to weld structural aluminum, the requirements are spelled out in AWS D1.2.  It includes design information.

RE: Weld values for aluminum

Hello everybody:

For question NÂș1, you can go to this site: www.alcotec.com

You will find there very good information on Aluminum welding works.

Good luck !

RE: Weld values for aluminum

The value of "F" is dependent on the aluminum alloy being used. Welding has an adverse affect on the strength and ductility of a number of aluminum alloys.

As an example, 6061-T6 aluminum in the wrought condition has a published tensile strength of 42 ksi. Most welding standards are happy to see an as welded tensile strength of 24 ksi.

Some alloys are time at tenperature sensitive. The more thermal cycles involved, the lower the tensile strength and the lower the ductility.

Preheating is not recommended with aluminum alloys regardless of the thickness. Limit the interpass temperature.

GMAW in the spray mode will produce better results (mechanical properties) than GTAW in many cases, especially on thicker sections.

And as with many base metals, clean, clean, clean. This includes the work area, work surfaces, and all hand tools. Do not handle cleaned materials (including filler metals) without wearing "clean" gloves. Weld within four hours of cleaning for the best results.

Best regards - Al
