May 28, 2016 · A welding procedure is being qualified for the welding of A709 grade 36 plates for cyclically loaded structures. Assuming this structure was for the construction of high way bridge. The welding process is SMAW, and the welding configuration is a single V-groove weld with a steel backing. The thickness of the test plate is 15.9 inches. Factors for Selecting the Right Stick ElectrodeJun 26, 2009 · Welding current. Some electrodes can be used with only AC or DC power sources while other electrodes are compatible with both. To determine the correct current type for a particular electrode, refer to the fourth digit of the AWS classification, which represents the type of coating and type of compatible welding current (see Figure 1). GUIDE SPECIFICATION FORAs additional welding processes and consumables are evaluated, the HPS Fab Guide will be updated to include those recommended for welding HPS 70W steel. All references made hereafter to AWS D1.5 shall mean the AASHTO/AWS D1.5M/D1.5:2002 Bridge Welding Code. 1.1 Fabrication With HPS The superior toughness of HPS 70W steel,

MIG wire for autobody work - Miller Welding Discussion

ASTM A709 grade 36 has a yield strength of only 36 ksi, but an ultimate tensile strength in the range of 58-80 ksi. A709gr30 would be more easily bent than A992, even though they have about the same ultimate tensile strength. Preheat and Interpass Temperature for - WELDING When the base metal temperature is below 32°F [0°C], the base metal shall be preheated to a minimum of 70°F [20°C] and the minimum interpass temperature shall be maintained during welding. For ASTM A709 Grade HPS 70W and ASTM A852, the maximum preheat and interpass temperatures shall not exceed 400°F [200°C] for thicknesses up to 1-1/2 in Steel grades according to American standards - A36, A709 - 04a Grade 36 250 [36] 400-550 [58-80] 20 21 Grade 50 345 [50] 450 [65] 18 21 Grade 50S 345-450 [50-65] 450 [65] 0.85 18 21 A913 - 04 Grade 50 345 [50] 450 [65] 0.85 18 21 21 [70] 54 [40] Grade 65 450 [65] 550 [80] 15 17 21 [70] 54 [40] A992 - 04a A992 345-450 [50-65] 450 [65] 0.85 18 21 Standards

A 36 is essentially the same as A 709 Gr. 36, so you can look up the tables in AWS D1.5. Another way to look at it is that A 709 Gr. 50 is essentially the same as A 572 Gr. 50, so if you have experience welding A 36 to A 572, it's the same as that.

Welding metals of dissimilar strengths - The FABRICATOR

Unfortunately, welding AR plate to softer or lower-strength steels (usually A36 or A572) brings with it the potential for cracking in the heat-affected zone (HAZ) of the AR plate. Here, you need to use a joint design such as a short, small fillet weld that can reduce heat input and overall residual stresses on the AR plate, and also find a a709 grade 36 specs - pneuscoolscharleroi.beChapel Steel stocks A709 Grade 36, A709 Grade 50 and A709 Grade 50W for the manufacture of bridges.
