Re: [MW:4391] Aluminium Welding

Dear  Elshan,

Thanks a lot for your reply, I do have a DC MIG power source will give it a try on the GMAW process for the same. 

Regards,

Dear Nimesh,
 
I have practicied many welding processes and consumables for welding of 50xx and 60xx grade AL.
 
you can use both procedures TIG and GMAW.
 
if you use TIG your machine and power should be set up on AC.
 
if you use GMAW your power should be DC. try to use ESAB make ER5356 or 5183 gmaw wire in DC current.
 
the Al you want to weld is non heat treated alloy. with above written GMAW wires you can get a very good result but dont pass the interpass temperature which is required to be max 130 degree c.
 
best regards,
Elshan.

Dear All,


Need to weld Aluminium of grade 5052 for 5mm thick plates in both BUTT and FILLET welding. Kindly suggest which type of power source (Arc, TIG, MIG) will be most suitable for this application. 

We tried using LH409 welding electrode (3.2mm ) in EP mode. We get a good weld result with BUTT joints but Fillet doesnt hold any strength , any reasons why ?

Heat tint (temper) colours on stainless steel surfaces heated in air // Heat tint

Introduction The colour formed when stainless steel is heated, either in a furnace application or in the heat affected zone of welds, is dependent on several factors that are related to the oxidation resistance of the steel. The heat tint or temper colour formed is caused by the progressive thickening of the surface oxide layer and so, as temperature is increased, the colours change.   Oxidation resistance of stainless steels However, there are several factors that affect the degree of colour change and so there is no a single table of colour and temperature that represents all cases. The colours formed can only be used as an indication of the temperature to which the steel has been heated. Factors affecting the heat tint colours formed Steel composition The chromium content is the most important single factor affecting oxidation resistance. The higher the chromium, the more heat resistant the steel and so the development of the heat tint colou...

The Schaeffler and Delong diagrams for predicting ferrite levels in austenitic stainless steel welds

Introduction Ferrite is important in avoiding hot cracking in during cooling from welding of austenitic stainless steels. 'Constitution diagrams' are used to predict ferrite levels from the composition by comparing the effects of austenite and ferrite stabilising elements. The Schaeffler and Delong diagrams are the original methods of predicting the phase balances in austenitic stainless steel welds. Nickel and chromium equivalents A 'nickel equivalent' is calculated for the austenite stabilising elements and a 'chromium equivalent' ferrite stabilising elements. These are used as the axes for the diagrams, which show the compositional equivalent areas where the phases austenite, ferrite, martensite (and mixtures of these) should be present. Although intended to show the phase balance of weld fillers, these diagrams can also be used to illustrate the phase balance of the 'parent' material. There are different diagrams for dif...
