Common use of General Requirements for Welding Clause in Contracts

General Requirements for Welding. The Contractor shall ensure only welders with proper certification through ABS and USCG may weld steel on this job order. The electrodes used throughout the work shall be suitable for use with the parent metal at each weld. Electrodes shall be received on the job in unbroken packages bearing the manufacturers' label or be otherwise marked. Certified statements shall accompany each shipment of electrodes to the effect that sample pieces, representative of each kind and size in each shipment, have satisfactorily passed the tests required by ABS and USCG for welding on the parent material. The Contractor shall provide the COR documentation certifying compatibility of electrode with parent material. The Contractor shall submit welding procedures to the COR prior to welding to a casting or forging. The procedure shall cover the type of weld process, welding electrode, pre-heat, welding sequence and stress relief required. All welding shall be smooth, tight, and free from undercuts, porosity, craters, and gas inclusions. Shell, deck butts, and flush seams shall be back chipped or gouged to sound metal from the closing side before welding. All sharp and/or rough edges shall be ground smooth and all weld splatter shall be removed. All welds for temporary dogs used during modifications or to secure plate in place while welding shall be ground flush with the surrounding metal. Assembly of all welded joints, before welding, shall be such as to secure proper gaps in butt welds and metal contact in fillet welds. Welding shall not be used to close openings larger than stipulated for each plate thickness by the ABS. Welding procedures, as to direction, length, number, temperature and sequence, shall be carefully planned to minimize distortion and locked-in stresses. Any welding to or of hull shell plating, watertight and/or oil-tight bulkheads shall be inspected by ABS. This includes the removal of existing plate, examination of the remaining surrounding plate, examination of the fit-up, and examination of the final welding Any welding shall use local grounding on and forward of frame 48 and on and aft of frame 108 and in all machinery spaces. The Contractor shall maintain a log of all welders who worked on the vessel throughout the repair period, each welder’s certification, and the repair activities on each welder worked. This log shall be made accessible to the COR at any time during normal business hours throughout the period of performance of this job order. Testing of welds, will apply where required.
