焊接就像缝纫,除了用火…. 这是永久连接两个独立材料或金属部件的最常用方法. 这个过程包括加热金属, adding a filler material that forms a pool of molten material, and then fusing the metal to form a permanent bond.
When the metal cools, a strong bond is formed. 事实上, 焊接材料具有更高的抗拉强度,比原始金属本身更坚韧. 通过高能、高温和高压,一块金属会变成全新的东西.
焊接的起源可以追溯到3000多年前的青铜时代. During that time period, it was known as forge welding. 这种早期形式的焊接由2块材料相互叠接而成, heated and hammered together until they joined.
今天,电已经取代了这一过程,通常被称为电弧焊接. 这种形式的焊接在19世纪被发现,现在被认为是连接金属的最有效方法.
Early welding consisted of hammering metal
人类使用的所有产品中,超过50%是由焊接制造的. You can imagine then there are many industries utilizing welding. Here is a look at the many industries employing welders:
焊接 occurs in the production of aircraft engine components.
修理破损的栅栏、大门和设备,焊接在农场里随处可见.
汽车 trailer and body manufacturing employs many welders.
1928年,卡内基大楼是第一座使用连续焊接梁的建筑. From this point on, welding was here to stay. Since the 1940's, riveting is the main process used.
不止一个 50万座桥梁 在美国各地都有建筑.S. That requires many welders keeping these structures intact.
Rail cars and rails require welding repairs.
焊接 plays an important part in shipbuilding and repair.
The Bureau of Labor Statistics (BLS) reports there are over 400,000 welders, cutters, solderers and brazers. Here are the industries employing the most welders.

谁是焊工? 焊工是能做出大多数人做不到的东西的人,今天的现代铁工, 金属工人和焊工负责建造我们每天看到的天际线. Whether one is looking at the NYC skyline or the Golden Gate Bridge, 焊工丰富了我们的风景.
焊接是一个总是供不应求的职业. They can find themselves in any of the industries mentioned above, from an offshore oil rig to a automotive manufacturing plant. 以下是主要职业:
焊工 – join metal parts by more than 100 different welding processes.
刀具 -利用热量切割和修整金属.
钎焊工 -将熔点低于华氏840度的两个或多个不同物体结合在一起. 只有添加的金属被熔化.
布雷泽 – connect thinner metals that higher welding temperatures can damage. 只有添加的金属被熔化.
使用电弧加热, 熔化并混合涂覆电极的熔融沉积物,以形成金属键.
利用电流在金属和焊棒之间进行焊接的过程. 它采用固定长度的电极, 还有一个电源, 加入各种不同的金属. The welding process is ideal for windy and outdoor conditions. Excellent welding process for thick materials.
使用电弧和气体的结合将金属表面熔在一起. MIG(金属惰性气体)或TIG(钨惰性气体)焊接通常用于更详细的工作, 如焊接金属管道. 两者都使用惰性气体,如氩气或二氧化碳,以及消耗性金属棒或电线来完成焊接.
焊机在自动送料的线轴上使用焊丝焊接电极. It's easy to learn but doesn't produce high quality welds.
Welder feeds welding rod to the TIG torch to make a weld. TIG welding allows for the welding of smaller objects. The welds are typically of higher quality than MIG welds.
精确的金属切割确保实现特定的形状,尺寸,设计和厚度水平. 切削包括使用切削工具去除不需要的金属材料. It is an essential process used across manufacturing industries.
The process of removing unwanted material with a cutting tool.
The process of cutting metal with a hot flame.
所有焊接过程的挑战是无限的安全隐患和风险. 以下是最常见的焊接危险:
Protective clothing should always be worn during the welding process. 需要佩戴的个人防护装备包括:手套, 皮革围裙, 面罩, 阻燃工作服和衬衫, 安全眼镜, 和紧身裤.
Dry gloves should always be worn to protect against electric shock.
眼睛被射伤, 热渣, 金属芯片, hot electrodes and bright lights are an everyday concern.
焊接时产生的高温和火花有可能引起火灾或爆炸. 焊接 should only take place in areas free of combustible materials.
焊接 fumes contain harmful complex metal compounds.
Intense heat, needed to melt metal, is produced by an electric arc.
手指和手很容易被热金属或熔融材料烫伤.
Small pools of molten metal are formed at the weld. 不应该穿非fr的衣服.
焊接过程中金属飞溅.
Burns to eyes are a top eye injury recorded each year. 电弧焊接产生的强光会对眼睛的视网膜造成损伤.
