in 2003, Jinan haitong welding technology co., Ltd. achieved from the management to the industrialization of the breakthrough, was established in Jinan high-tech development zone.
marine welding a dozen years of professional acting experience of world famous brand welding equipment, exercise sea welding customer-oriented, ability to provide technical service for users. sea pass welding accumulation has large user real applies of automation set solution programme of experience, formed has a support to welding, and automation, and non-standard machinery design, and software development for main of development and technology service team, and completed has independent intellectual property of "NC more axis linkage flexible arc welding Center" control system of development and development, implementation has full significance of workpiece more movement axis, and torch precision movement axis, and wire movement axis, and welding technology parameter of accurate control, more axis linkage of arc welding technology of automation welding system. so that the welding of complex automation of the whole process become extremely available, simple, reliable and stable.
in 2004, haitong welding "CNC multi-axis flexible welding centres" by national Ministry of science and technology projects to focus on supporting the development of advanced technology projects, and batch production. applications in aerospace, defense industry, petrochemical industry, boilers, pressure vessels, vehicles, containers and other industries. and exported to overseas, has been lauded by customers at home and abroad.
sea welding is committed to using state of the art welding technology of traditional arc welding methods. the development of variable polarity plasma arc welding, plasma arc welding, double, single and double wire submerged arc welding wire welding, to provide users with high performance, materials, energy-saving, high quality complete solutions.
haitong has a welded by non-mechanical design engineer for many years, with an optimized design of welding to meet user requirements. sea-pass welding and gradually form a modular design, standardization of production, formed for variable polarity plasma, TIG, plasma, MIG/MAG, submerged arc welding (SAW), the longitudinal seam arc welding methods, girth, non-round curve of the second weld, gantry, cantilever, machine operation, positioner and robot production capacity of complete set of quilting frame.
at present, the welding is the sea and Ukraine Barton welding Institute National Academy of Sciences actively cooperation, jointly to undertake major projects for international cooperation of science and technology. we believe that communication and collaboration with world renowned scientific research institutions, its introduction and industrialization of advanced technology and equipment, can not only improve our company's technology research and development, will bring considerable economic benefits.

haitong welded welcome you with us to establish relations of cooperation, and invites you to share the sea advanced welding technology and services.
