forced concrete structure reinforced with an

overviewRein

Since the reform and opening up, with the national economy's rapid and sustained

development of a reinforced concrete structure built, reinforced with the development

of technology has been great. Therefore, to promote the use of advanced technology

Reinforced

into

categories linking welding machinery and steel. There are six types of welding steel

welding methods, and some apply to the prefabricated plant, and some apply to the

construction site, some of both apply. There are three types of machinery commonly

used reinforcement linking method primarily applicable to the construction site. Ways
