What is bridge welding?
Bridge welders join the metal parts of a bridge. In this role, you weld, braze, and heat cut pieces of metal for both fixed and movable bridges. Some employers may have you fabricate and assemble metal parts to aid in the durability of bridges.
Why is welding used in bridges?
This metal expansion joint allows the bridge to contract and expand with temperature changes. On the back of that plate, stud welding holds it in place by anchoring it to the concrete sets. Stud welding also creates adhesion between other plates and steel to concrete and reinforced mesh.
How bridges are welded?
The most common welding processes used in bridge construction are manual shielded metal-arc welding with covered metal electrodes and submerged arc welding for carbon and low-alloy steels (ASTM Specifications A 36 and A 588).
How do you become a bridge welder?
Even though some bridge welders have a college degree, it’s possible to become one with only a high school degree or GED. Choosing the right major is always an important step when researching how to become a bridge welder.
How much do bridge welders make?

How bridges are connected?
A typical connection is a splice in the main longitudinal beams of a bridge. These should normally be located where a change in the section size is appropriate. In medium span bridges this is often near the points of contra flexure where the bending moments are lower.
What is a weld bridge and how does it work?
Working in limited access areas, or where contact with the weldment must be avoided, welders will work from what is essentially a scaffold plank but is a called a “weld bridge”. 3. Similar to #2, automated welding machines run on a track that is sometimes called a bridge.
What is structural welding?
Structural welding is a process by which the parts that are to be connected are heated and fused, with supplementary molten metal at the joint. A relatively small depth of material will become molten, and upon cooling, the structural steel and weld metal will act as one continuous part where they are joined.
Where to start welding on a bridge?
Usually at, or as close to the landing area of the bevel as possible. Now the welder can start up on the bridge, has something to weld to, and it’s easier to fill the gap with good weld.
What is welding and how does it work?
Welding is the process that involves joining two pieces of metal together by applying heat. The process of welding can be performed in different ways. Some of the most popular types of welding are:
