Yes I agree with Goswami sir. It is not easy to qualify with impact with low temperature. Need to control & record minor data for conclusion of any results,including position of welding, Groove geometry, no of passes, heat input & deposition of each pass,gas composition/mixtures,& finally manufacturer/ brand.

[MW:30092] Shear anchor welding

Dear Experts, I would like to get your advice and opinion  about the welding og above subject. We have to weld  1000 shear anchors on stainless steel 10 mm thick  Following are the quality of the plate and anchor. Plate      SA 240 Type 304 Shear Anchor    16x150mm S235J2+ C470 I would like to know whether we use  shear anchor welding machine to do the welding. These are the two different materials and chemical compositions are different we have to use  SS 309l welding rods and do the manual welding using SMAW or FCAW welding process.

[MW:30091] concrete base in destilation tower

Dear Group,   Please consider attached pictures.   This is a de butanizer tower in cryogenic gas process unit.   Due to low process temperatures, and even with isolation, there´s ice that is created in some sections of tower and it´s pipes.   Ice blocks, with some environment conditions, begins to melt in form of water drops, which falls from a high altitude and hit concrete base of tower.   As you can see, concrete base has damages due to impact of water drops.   Now, our theme is determinate which steps we could follow to recover the concrete base to original conditions.   I´d like to know is it´s necessary a civil engineering develop which could determine action to take.   Please if you can give me some references of your experiences or codes/standars to manage this kind of cases   Thanks in advance   Best regards   Miroslav Tadic Integrity Enginner Telef.
