Beamsplitters: Divide, combine & conquer
When you need to separate or overlap two beams on the optical bench or in a product design, the solution is most often the humble but elegant beamsplitter. In this tech note, we''ll look at the types of
How to perform welding inside the beam splitter box
Welding inside a beam splitter box requires careful preparation, proper access, and controlled heat to ensure structural integrity without warping the steel.Preparation and SafetyBefore welding, ensure the beam is clean and free of rust, paint, or mill scale, as contaminants can weaken the weld and produce hazardous fumes . Use an angle grinder to bevel edges if necessary, which allows for deeper weld penetration . Always wear safety gear, including an auto-darkening helmet, leather gloves, and a fire-resistant jacket . Ensure the area is well-ventilated, especially when working inside a confined box.Access and PositioningConfined spaces inside a beam splitter box can make welding challenging. Use magnetic welding squares or clamps to hold plates or stiffeners in place while tacking . If adding reinforcement, cut stiffener plates that fit between the flanges and weld them to both the flanges and the web . Tack weld first to secure the pieces before performing full passes.Welding TechniquePreheat the steel if it is thick or high-carbon to reduce the risk of cracking. For example, preheating to around 250°F and keeping inter-pass temperatures below 450°F is recommended for AR400 or similar steel .Use MIG or Stick welding depending on accessibility and material thickness. Adjust amperage to match the steel thickness .Perform multiple passes with controlled heat to avoid warping. Allow the weld to cool gradually between passes.For confined areas, consider shorter weld beads and staggered passes to minimize heat buildup and distortion.Post-Weld ConsiderationsAfter welding, inspect all welds for cracks or incomplete fusion. If possible, perform a dry cycle test to ensure the hydraulic ram moves smoothly and the beam maintains alignment . Reinforce critical areas with gussets or additional plates if necessary to prevent bending under load .SummaryWelding inside a beam splitter box is feasible with proper preparation, careful positioning, and controlled heat management. Key steps include cleaning and beveling steel, using tacks and clamps for alignment, preheating thick steel, performing multiple controlled passes, and inspecting welds for integrity. Reinforcing with stiffeners or gussets can improve structural strength while minimizing the risk of warping or failure under hydraulic pressure .
