焊接就像缝纫，除了用火…. It is the most common method for permanently joining two separate materials or metal parts. 这个过程包括加热金属, 添加填充材料，形成熔化的材料池, 然后熔合金属形成永久的键.
当金属冷却时，就会形成牢固的粘结. 事实上, the welded material has greater tensile strength and is tougher than the original metal itself. Through high energy, heat, and pressure a piece of metal is transformed into something brand new.
焊接 origins can be traced back to the Bronze Age, well over 3000 years ago. 在那个时期，它被称为锻造焊接. This early form of welding consisted of 2 pieces of material being lapped over one another, 加热，敲打，直到接合.
Today, electricity has replaced that process, commonly known as ARC 焊接. This form of welding was discovered in the 1800s and is now recognized as the most efficient method for joining metal.
早期的焊接是用锤击金属
焊接 is responsible for creating over 50% of all the products humankind uses. 你可以想象有很多行业使用焊接. 以下是许多雇佣焊工的行业:
焊接发生在飞机发动机部件的生产中.
Fixing broken fences, gates and equipment, welding occurs everywhere on a farm.
汽车挂车和车身制造业雇佣了许多焊工.
In 1928, the Carnegie building was the first building to use continuously welded beams. 从那时起，焊接就一直存在. 自20世纪40年代以来，铆接是使用的主要工艺.
不止一个 50万座桥梁 在美国各地都有建筑.S. 这需要许多焊工保持这些结构的完整.
Pressure equipment, piping, heaters, repairs, and equipment upgrades require welding.
61% 所有的焊接工作都在制造业.
焊接 of turbines, casing and components takes place across thermal power plants.
轨道车辆和轨道需要焊接修理.
焊接在造船和修理中起着重要的作用.
美国劳工统计局(BLS)报告称，这一数字已经结束 40万名焊工、切割机、焊工和钎焊工. 以下是雇佣焊工最多的行业.
| 行业 | 就业 |
|---|---|
| 金属制品制造业 | 85,750 |
| 机械制造 | 50,980 |
| 汽车车身和挂车制造 | 20,000 |
| 就业服务 | 15,500 |
| 船舶制造 | 11,790 |
| 铁路车辆制造业 | 4,260 |
| 发电、输配电 | 1,200 |
| 天然气分配和管道 | 800 |
| 煤炭开采 | 620 |
第三大焊工雇主是Trailer MFG. newbb电子平台安全手套, glasses and garments keeps these workers same from hazardous conditions, 无论是削减, 热或火花.
德克萨斯州被称为焊接工作之都，这是有充分理由的. 以下是雇佣焊工最多的州.
| 状态 | 就业 |
|---|---|
| 德州 | 49,510 |
| 加州 | 26,550 |
| 俄亥俄州 | 17,310 |
| 宾西法尼亚 | 15,320 |
| 威斯康辛州 | 14,250 |
谁是焊工? A welder is someone who build the things most people can’t… Today’s modern ironworkers, metalworkers and welders are responsible for building the very skylines we see every day. 无论是纽约的天际线还是金门大桥, 焊工丰富了我们的风景.
焊接是一个总是供不应求的职业. 他们可以在上面提到的任何行业中找到自己, 从海上石油钻井平台到汽车制造厂. 以下是主要职业:
焊工 -通过100多种不同的焊接工艺连接金属部件.
刀具 -利用热量切割和修整金属.
钎焊工 – join two or more different objects with a melting point below 840 degrees Fahrenheit. 只有添加的金属被熔化.
布雷泽 -连接较薄的金属，较高的焊接温度会损坏. 只有添加的金属被熔化.
使用电弧加热, melt and mix molten deposits of the coated electrode to create a metal bond.
焊接 process that uses an electric current between the metal and the welding stick. 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. 焊接工艺是理想的多风和室外条件. 对厚材料具有优良的焊接工艺.
Uses a combination of electric arc and gas to fuse metal surfaces together. MIG (Metal Inert Gas) or TIG (Tungsten Inert Gas) welding are common for more detailed work, 如焊接金属管道. Both use an inert gas such as Argon or Carbon Dioxide along with a consumable metal rod or wire to complete the weld.
Welder uses a wire welding electrode on a spool that is automatically fed. 它很容易学，但不能产生高质量的焊缝.
焊工将焊条送入TIG焊枪进行焊接. TIG焊允许焊接较小的物体. 焊接通常比MIG焊接质量更高.
Precise metal cutting ensures specific shapes, sizes, designs, and thickness levels are achieved. Cutting involves removing unwanted metal material, using a cutting tool. 它是整个制造业中使用的基本流程.
用切削工具去除不需要的材料的过程.
用热火焰切割金属的过程.
The challenge across all welding processes are the limitless safety hazards and risks. 以下是最常见的焊接危险:
焊接过程中应始终穿着防护服. 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.
应始终佩戴干手套，以防触电.
眼睛被射伤, 热渣, 金属芯片, 热电极和强光是人们日常关心的问题.
The intense heat and sparks produced when welding can potentially cause fires or explosions. 焊接 should only take place in areas free of combustible materials.
焊接烟雾中含有有害的复合金属化合物.
熔化金属所需的高温是由电弧产生的.
Fingers and hands can easily be burnt due to hot metal or molten materials.
在焊缝处形成小的金属熔池. 不应该穿非fr的衣服.
焊接过程中金属飞溅.
眼睛烧伤是每年记录的最严重的眼部伤害. The intense light associated with arc welding can cause damage to the retina of the eye.
Personal Protective Equipment (newbb电子) should always be worn when welding. 在newbb电子平台安全，我们的目标是确保焊工能够安然无恙地回家. 我们自豪地制造焊接齿轮, 从焊接眼镜, 焊接手套到焊接服装.
Since we manufacture our welding products in our owned manufacturing facilities, we know a little something about the process and what’s needed in keeping welders protected. Below, you will find some insightful welding information and links to all the welding gear we offer.
