    • PURPOSE: An arc brazing method of high-strength steel sheets is provided to keep the strength and corrosion resistance of a high-strength steel sheet by minimizing thermal damage. CONSTITUTION: An arc brazing method of high-strength steel sheets(11a, 11b) satisfies the following a first general formula. The first general formula is ΔH=(H1-H2)/H1×100Δ10 %. The H1 is the hardness of a high-strength steel sheet before welding. The H2 is the lowest strength of a high-strength steel sheet during welding. The ΔH is the reduction ratio of hardness of a high-strength steel sheet in the softened area. The Vickers hardness of a high-strength steel sheet is higher than 250Hv.
    • 目的:提供高强度钢板的电弧钎焊方法,通过最小化热损伤来保持高强度钢板的强度和耐腐蚀性。 构成:高强度钢板(11a,11b)的电弧钎焊方法满足以下第一通式。 第一个通式是ΔH=(H1-H2)/ H1×100Δ10%。 H1是焊接前的高强度钢板的硬度。 H2是焊接时高强度钢板的最低强度。 ΔH是软化区域中的高强度钢板的硬度的减少率。 高强度钢板的维氏硬度高于250Hv。

    • PURPOSE: A structure and method for brazing of steel sheet and pipe joint in solar heat collector are provided to prevent the sheet and the connection pipe from being overheated regardless of thickness and size of a sampling member. CONSTITUTION: A connection pipe(20) includes an outer surface, which is inclined at a predetermined angle. The connection pipe(20) is inserted into a heat collecting plate(10). A longitudinal sheet part(37) is formed between a tip of the connection pipe(20) and the heat collecting plate(10). An insertion member(31) is inserted into a slot formed in the longitudinal sheet part(37). A filler metal(32) is positioned at an upper gap section(34) of the heat collecting plate(10). A heating source(33) is provided to heat the upper gap section(34) in such a manner that the insertion member(31) and the filler metal(32) are molten, thereby welding the connection pipe(20) to the heat collecting plate(10).
    • 目的:提供一种用于钎焊太阳能集热器中的钢板和管接头的结构和方法,以防止板材和连接管过热,而与采样构件的厚度和尺寸无关。 组成:连接管(20)包括以预定角度倾斜的外表面。 连接管(20)插入集热板(10)。 在连接管(20)的前端与集热板(10)之间形成有纵片部(37)。 插入件(31)插入在纵向片部分(37)中形成的槽中。 填充金属(32)位于集热板(10)的上部间隙部分(34)处。 设置加热源33以加热上部间隙部分34,使得插入部件31和填充金属32熔化,从而将连接管20焊接到集热器32上。 板(10)。
