CUTANDWELD
Metal, mastered — welding techniques, cutting and fabrication guides, plus handy everyday calculators.
From converting plate thicknesses and preheat temperatures to crunching waste percentages, counting down to a project deadline, working out a GPA, and splitting the crew lunch bill, CutAndWeld pairs handy everyday calculators for the shop with practical guides and a richly illustrated museum. Cut cleaner, weld stronger.
Free Tools & Calculators
Handy everyday calculators for the shop — age calculator, GPA calculator, percentage calculator, unit converter, date calculator, countdown timer, tip calculator, and random number generator.
Age Calculator 🎂
Work out an exact age, or the age on a given date, down to the year, month, and day — handy for eligibility checks, milestone planning, and how long that old rig has been in service
GPA Calculator 🎓
Add up your course credits and grades to compute a weighted GPA — useful for students working through a welding program, trade school, or any other course load
Percentage Calculator ％
Work out percentages, percentage change, and what share one number is of another — great for material waste allowances, discounts on steel orders, and comparing quotes
Unit Converter 📏
Convert length, weight, and temperature between metric and imperial — handy for plate thicknesses in mm and inches, stock weights, and preheat temperatures in °F or °C
Date Calculator 📅
Find the number of days between two dates, or add and subtract days from a date — perfect for project deadlines, certification renewals, and delivery lead times
Countdown Timer ⏳
Count down to a project handover, certification exam, delivery, or shop open day and watch the days, hours, minutes, and seconds remaining update live
Tip Calculator 💵
Work out the tip and total on any bill and split it evenly across your group — for the crew lunch run or any night out after a long day in the shop
Random Number Generator 🎲
Generate random numbers in a range for drawing giveaway winners, picking sample pieces for inspection, or settling any either-or decision fairly
Museum of Metal & Fire
Wander an immersive museum of metal and the fire that shapes it — four wings covering the welding and cutting processes that join and sever steel, the metals and alloys behind every build, the smithy and its ancient craft of forge and anvil, and the great metal structures that changed the skyline, each in its own gallery, so you can get to know the story behind every process, material, and landmark: how each one came to be, what makes it matter, and the role it plays in the work we do at the bench today.
Tour the museum →From the Journal
Fresh guides on MIG, TIG, and stick welding, plasma and laser cutting, metal fabrication, and welding safety, plus equipment reviews and practical tips for cutting cleaner and welding stronger.
