Product Application

APPLICATIONS
CARVER 7018 is suitable for all sorts of joining, repairing and fabrication of structural works medium and high tehsile steels of grade 540 N/mm2. The applications include; welding of structures, highly restrained joints, bridges, railway coaches & wagon, plants, ships, tugs, barges, trawlers, dredgers, storages, tanks, boilers, pipelines, grills ets. Recommended where toughness and reliability of weld joint are of prime importance.

Technical Specifications

FEATURES
CARVER 7018 is a basic coated low hydrogen iron powder electrode suitable for welding heavy structures, high tensile strength jobe where impact strength at sub- zero temperatures are required. With an increased metal recovery due to the presence of iron powder, enhances the welder to complete the job faster. The basic coated formulation ensures a defect free radiographic quality weld. The superb and well established flux formulation ensures excellent perfor- mance of the electrode in AC/DC (+) in all welding positions except vertical down. We can supply flux cored wires also.

OPERATIONAL CHARACTERISTICS
• Uniform and soft metal transfer.
• Easy to control weld pool and slag.
• Suitable in AC70 V/DC (+) and AC too.
• Excellent lmpact Resistance and Ductility.
• High tensile strength and excellent toughness in sub-zero temperatures.
• Suitable for highly restrained joints
