Q: We're a construction equipment manufacturer that is finding that our customers increasingly require more components designed and manufactured from high- strength steels such as A5. This means we have to preheat and follow slow cooling conditions, but even then certain joints or components always seem to crack. We typically have weld cracking on root passes of joints, such as the end of a pipe welded to a base plate or with other highly constrained joints. Any suggestions on how to prevent cracking in the root pass? A: Weld cracking is fairly common in high- strength steels (HSS). Generally speaking, the reason there are more issues with cracking on HSS is that it lacks give or flex, known as ductility. They are also susceptible to hydrogen cracking, martensite formation, and accelerated cooling rates can have detrimental effects on heat- affected- zone (HAZ) hardness values. As you mentioned, preheating and slow cooling require more detail that will greatly influence whether you are successful at preventing cracking. The 4. 13. 0 steel, depending on thickness, will probably require a preheat somewhere around 4. F with a maximum interpass temperature of 7. 305-350, 1987-1998, OE Roller Cam: Small Block, LT1.

The A5. 14 will require a preheat temperature of 2. F based on thickness, and a maximum interpass of 4. F. Joint preparation is also important. Make sure there are no gouges, grease and contaminants, or dross remaining from the cutting or beveling operation. For these types of steels, be sure to use a low- hydrogen process and check that the product has been stored properly. Ford Timing Belts & Chains.

Also, be sure you are following the manufacturer's specified welding parameters, and pay attention to voltage and electrical stick- out (ESO). Excessive ESO or voltage can increase hydrogen pickup from the atmosphere. Since the root pass is where the cracking problems occur, make sure the bead profile is slightly convex and has a good depth- to- width ratio, ideally about 1 to 1. Centerline cracking sometimes is caused by the throat of the weld. If it is concave and shallow, it will not be able to accommodate weld shrinkage and the resulting residual stress. This is especially critical for highly constrained joints. CAD/CAM Software; Consumables. Eliminating weld cracking in restrained joints. The A514 will require a preheat temperature of 200 to 350 degrees F. The other extreme is having a weld bead that is very deep and narrow (for example, an excessive depth- to- width ratio), resulting in centerline cracking problems. One more important thing to consider is bead sequencing. If the part has multiple welds, consider sequencing them differently to balance the residual stresses. If there is only one weld, as in the example of pipe to plate you mentioned, then try splitting the weld up into thirds or quarters. Using a clock face for direction, try welding from 1.
