In general, butt joint welding is divided into two-sided welding welded on both sides and the back gouging must be applied due to poor welding quality at the first welding layer of the first one-sided welding. (Call completed joint penetration, See What is CJP in welding) For one-side welding method, a backing material, which is a backing material that prevents melting of molten metal, is attached to the backside of the base material, and then the welding wire is lowered to form an arc between the base material to weld the base material. Welded Chill Plate (or Permanent backing strip, … Continue reading What is Chill Plate in Welding


General Defects in construction usually cannot be detected after the fabrication and welding work has been finished. During in shop fabrication the precise accuracy of this process will govern the final accuracy of the assembly unit. The surveyor should engage in frequent patrol inspections, taking every possible opportunity available on the way to or from the block yard to carry out block inspections or from building berth for tightness tests etc. He has to pass the fabrication shops to see the prefabrication process such as surface treatment, marking, gas cutting, bending, bracket profile, build-up section, tack welding etc. When defects … Continue reading HULL SURVEY: FABRICATION & ASSEMBLY PROCEDURE
